> do I have to cast values from text boxes into ints?
Not usually, because PHP and MySQL take care of converting for you, 99.9999%
of the time.
But what you get from a FORM (or a GET URL) are all strings. The HTTP spec
doesn't have any way to distinguish one data type from another. It's all
strings.

Actually, PHP didn't turn them into ints in that case -- MySQL did.

I'm not finding the actual problem here...
Can you pin-point it for us?

> Vent1MaxFlow
> Vent2FixedFlow
> The '1' and the 'xxxFlow' are from columns in a set of tables.
