Thanks for this info as it kinda worked.
I updated the radio button info as you suggested and now when I use the form it does write to the database. However when I go back and look at the record from the participant_data_Prifile page, all of the data repopulates on the screen except for the info that I checked in the radio buttons. The following is how I made the updates:
<th>Shirt Size:</th>
<td><input type="radio" name="shirtsize_1" id="shirtsize_1" value="<%=String(WAATKparticipantdata.Fields.Item("shirtsize_1").Value==null?"S": (WAATKparticipantdata.Fields.Item("shirtsize_1").Value)).replace(/"/g, '"')%>" />
[ Small ]
<input type="radio" name="shirtsize_1" id="shirtsize_1" value="<%=String(WAATKparticipantdata.Fields.Item("shirtsize_1").Value==null?"M": (WAATKparticipantdata.Fields.Item("shirtsize_1").Value)).replace(/"/g, '"')%>" />
[ Medium ]
<input type="radio" name="shirtsize_1" id="shirtsize_1" value="<%=String(WAATKparticipantdata.Fields.Item("shirtsize_1").Value==null?"L": (WAATKparticipantdata.Fields.Item("shirtsize_1").Value)).replace(/"/g, '"')%>" />
[ Large ]
<input type="radio" name="shirtsize_1" id="shirtsize_1" value="<%=String(WAATKparticipantdata.Fields.Item("shirtsize_1").Value==null?"XL": (WAATKparticipantdata.Fields.Item("shirtsize_1").Value)).replace(/"/g, '"')%>" />
[ XLarge ]</td>
Did I not do this correctly?
