[FX.php List] Problem with double submissions

[Gjermund Gusland Thorsen]

Heh, I would use a string for every form <<CCYYMMDDHHIISS>> made at
the same time as the form,
then I would store that value in a unique field in FileMaker, then
when ['errorCode'] == 504 shows up...

tada! You could trap the error in php.

Then they can submit as many times as they want, and you only keep the
first one, or you can also choose to store updates if need be.
