The original insert was generated using the Wizard. I removed the first insert and and added a replacment Insert block using Data Assist. After adding the concat code it inserts and updates the nickname fine. Awesome!
1) There is a DW warning regarding the "Check New Username" server behavior. I believe that this is checking as if the kids have login (In this case the parent's have login and they are setting up the kids unique registration.) and may need to be removed and replaced/edited? Or did I miss something in the setup?
2) I am not clear on how to read and edit the insert syntax used by DataAssist. I need to edit the insert for the current registration date statement: 'NOW()'
"".((isset($_POST["kidRegDate"]))?$_POST["kidRegDate"]:"") ."" . "|" .
3) Confirmation Email is sent with no value for the kidNickname. Just a blank. Suspect that the new concat variable needs to be stated so how and somewhere in the update code?
