Thanks for taking the time to read my question.

I have a form on which users enter info. The only required field is the
product code. I have it that if there is no value in the product code field,
they can't click the button to add the new info. Even if they add all data,
then delete the product code, the button becomes inactive. The only way they
can get around this.. and they have :( is to add a bunch of spaces.

How do I test for an indefinate amount of spaces?

Thanks,

Brad
