TEMA:

A think that the script is good because if I have not dupplicate value, it's record and if I have dupplicate value is Not record (but I have a blank page !)
It's "just" the error message

I follow the same method that for PSW Dupplicate > 4 scripts
2 on Field Drop-down (listGraphicWorkshop)
1 on Form pieces in the Before Form section
1 on Submit pieces and in the Begin Submit section


Thank's to spend a lot of your time to see it.
I wait ...

Hi,

this happend because "exit" is there, if someone enters duplicate value it is on exit, and that is the reason why there is empty page.

You can add specific message before exit, like:
or if you want to redirect it on specific page if value is duplicate then:Please test it and then let me know the result

Sorry Tihana but I have no change !
Only the same blank Page ...

Can we have a error message on the form page like we have on Dupplicate Psw fonction ?

You can test it, with your Front Login transmit.
Because all data are already save.
Then the form must to display error, if the script is correct .

Hi,

script is correct, could you please check phperror log?
And if there is something useful please post it here

If you can't find php error log, ask your host provider for this
