Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Totaling on a list when filtered.

    Continuing on from my earlier thread on the same topic http://msgboard.alphasoftware.com/al...ts-and-filters I have an additional problem which is calculating totals.

    When the list is unfiltered, I calculate totals by specifying totals in the list field tab and it works fine (see attached pic).

    When I filter the list by date as described in the other thread, I get the Javascript error shown. FWIW, it doesn't matter in this case whether the list is filtered by US or UK date ... same error message.

    The odd thing is I have a child list attached to this list which calculates totals in the same way, and it works fine when filtered against a unique ID from the parent list.

    Thanks for any assistance.

    A video showing the difficulty.

    The child is linked to the parent, but is irrelevant to the difficulties, as I have commented out the code on the child totalling and left it in, and it makes no difference either way.

    http://screencast.com/t/SAbLbwth09F

    So, to recap ... before the list is filtered using the list control, server side filter, the totalling works. Once the filter takes place, then we get javascript errors. Also, the list isn't refreshed ... but that is not surprising after the javascript error. Redisplaying the component works and shows the correct values.

      I've tried to duplicate what you've got running... and I'm not getting errors. Totals are coming out ok before and after a date filter.

      I'm not crazy about a couple of things, but they don't seem to hurt. I wouldn't choose "Total" for a field name... it's going to get you into trouble one day.
      Plus... you've got both the Server-side and Client-side summary checkboxes checked in the List Fields Pane... I can't see why you'd need the client-side checked.
      You're setting up a variable this._total in a List event. Not sure you need that. I didn't put it in an the UX and List are ok without it.

      Again... none of these items are causing the error.

      I would put a debugger; statement into the event list event where you're getting the total value and then run under Chrome or Firefox... right-click and Inspect element on anything to show the scripts etc, and the refresh so the code and debugger will run. See if that reveals anything.

      Your first UX, rendered is showing 0 for the line item that should be 100. Had you run the date filter just before?

      The other thing to do is a quick new UX with one List, date filter, and summary... see if that works.

        Hi again David,

        Using the method outlined in the video http://www.ajaxvideotutorials.com/V1...maryValues.swf didn't work. The original code I had there I copied from a (different) Selwyn video, fwiw.

        I changed the code as follows (and changed the field name Total to TotalPaid )

        Code:
        var paidtotal = {dialog.object}.getListServerSideSummaryValue('Header','TotalPaid','total');
        $('TOTALMSG').innerHTML = paidtotal;
        Now it works ... go figure!

        Thanks once again for your time and patience.

        Regards

        Phil
