Build a table in a form where user can input values and save them.

Normally QuickBase associates one form control with one field. But in your case you basically want five "Likert Scale" radio buttons for one answer field.

Using the IOL technique you can transform each answer text field (shown below for fid=7) into five radio buttons with this simple script:

var markup ='
<input type="radio" name="_fid_7" value="SD">Strongly Disagree
<input type="radio" name="_fid_7" value="D">Disagree
<input type="radio" name="_fid_7" value="N">Neither Agree Nor Disagree
<input type="radio" name="_fid_7" value="A">Agree
<input type="radio" name="_fid_7" value="SA">Strongly Agree
';
$("#_fid_7").replaceWith(markup); 

The resulting form section will look like this although it still represents only one text field:


If you want to arrange your answer using a table or with some other attractive style you just modify the markup to appropriately surround the five radio buttons.
