Multiple questions on same screen: radio buttons (case 1497)

[jarvis24]

Here is a revision that shows you how to do multiple radio button questions on one page. It's essentially the same as just one. The big difference is that you now have more variable names. Normally, you would just have your MediaLab variable name match the HTML form variable name. Since you can't get away with this now, this is what you can do..

Create additional custom items in your questionnaire with the additional HTML form variable names you want to keep. If you do not include a filename for the items, then MediaLab will know they are just placeholders for additional variables. Check out the attached sample. It lists some extra custom items at the end that have no file names. But because the variable names are used in an HTML form, MediaLab will save the data when it's collected.

Remember these html forms can be edited easily in any text editor like the Windows notepad.exe editor.

I've succeeded running multiple radios and obtaining the data from each of the items. However, for the empty custom items in the questionnaire (the ones that stand there as dummies just to capture data on their variable name), medialab seems to force itself to display an html page (despite the fact I did not name a file!) - which leads to an error screen on the browser (no page available). How do I convince medialab to just use the added custom lines for data saving from the previous html file rather than trying to display additional custom items? Thanks!

May be a version issue. The feature that gets MediaLab to skip any custom item without a filename came in v2006.1.28. If you have a version that's prior to that, try installing the latest version from the download page.

I'm trying to do the multiple questions per screen but i'm not able to do that. How do i do that?
Also, i'm trying to open the Questionnaire file on the zip file posted, and it is empty. Please, i need help with this.
Thank you.

barbara--you need to copy the zipped files to a folder before you can work with them. If you try to open the .que file while it's still in the zip file, it will appear empty.

I am trying to adapt the multiple ratings radio custom item for my own use, but I am having difficulty getting a backgroud image to display. For our purpose, we have 200 images that we would like to display on the screen one at a time and have the subject rate the picture on two scales. So I would like the image displayed at the top with the two ratings below it. I am able to get the scales to work, but the image is not showing up. I have inserted the following code:

<IMG SRC="pic.bmp">
ml.sub "pic.bmp" = <ml.bg>

And have the path name to the picture under BackImage in my questionnaire file.

Attached in the zip file is the custom item as well as the que file that references it.

Thanks for the help!

Can you edit your post to include a zip file with what you've got so far? I'll take a look.
