I have this form: http://www.waggelrevue.nl/Form_Waggelre … lrevue.php
I save my data in Mysql.
When I delete the table there and submit the first form, everything is fine.
But when a second form is submitted, I get this warning:
Warning: [ err 2/line 444/datasavemysql.cls.php] A non-numeric value encountered

The data is stored in the table but the submitter gets no confirmation.
When the submit button is used for the second time, there is a confirmation and the data is stored for the second time in the table.

It happened in version 2.4, so I upgraded to 2.9 and it still happens.

What am I doing wrong?

Hi Toon,
Take a look at the values being submitted to make sure their correct with what the table is setup for. Otherwise try manually deleting the table again and reposing to confirm problem. If it still persists I would open a support topic.
