please use your second script, because in ff_getSubmit you can use in submit pieces, not in form pieces.
That is the reason why you get error using this in form pieces
using this (check if email is already entered), you check for field which you want.
If you want I can check it directly in your form, and apply the code there, but I need backend link, login information, form name, and field in which you want to add this.
Use this tag:
[confidential]
[/confidential]
I will check everything, and find where is a problem
you can't use this script on that way. Basically, this script is connect to one field, in your case listAtelierGraphique, am I right?
Then you need to use everything, validation, actionscript, before form pieces, begin submit (same as in documentation), and in form pieces, you can't use ff_getSubmit because this is for submit pieces.
For this you need select directly value from database, on the same way as it is described in documentation.
If you can give me access to this "#__specifictable", it would be great
I will see how to check this and let you know, please give me some time
