With the extra hidden field on the form I've got the relational table to display the optiongroupID properly and the MRT is working fine now. The other problems I mentioned in a previous post were unrelated to this and I have now solved them except for the two notices of undefined varaiables that appear at the top of the page. They are:
$WA_masterKeyValue = "".$_SESSION['WADA_Insert_products'] ."";
$WA_masterKeyValue = "".$_SESSION['products_ProductID'] ."";
How can I get rid of these?
Also I found that the sequence of adding the repeat region and repeat selection seems to be critical to the MRT working correctly, do you really need both? I got the MRT to work by trial and error but could you add a brief note on the correct method and sequence to add these repeat regions.
Previously you opened a support ticket for me, but I prefer to work by trial and error with help from you. I find I get to understand the subject better this way.
