Thanks Jason, but I have just within the last few minutes figured out a way to get it to work.
What I have to do is take the radios provided remove any binding, then add the value="XX" to each radio button, then from the server behaviours panel + button I choose Dynamic Form Elements -> Dynamic Radio Group and select the show data from the WADA recordset.
It's a shame it doesn't work straight from the wizard for either the radios or the menu. Is this always meant to be the case? The update page for radios and menus always fails to pull the correct data from existing records.
I now have a big problem with updating a file upload. The initial insert page works great, but the update will not. I'll post in that forum for that.
