In addition to my earlier post, I'll also want to do the following...:

One filed of mine should always be either CN, EF, or MGF. Can I verify that this field is one of these before submitting?

Another Field will be in the format:

LLL-NNNNNN-NNNN

Where L is a letter, and N is a number

Can I check the validity of this one too before submission? Might it be easier (?) to split up the three seperate parts of it, like Microsoft do with their product keys?

all thanks is muchly appreciated.

And in addition to that, I also want to replace a field with a text area (like the signature. I can make the text area, by copying the signature one, but on clicking apply changes I'm told tht the field (which is mandatory) is not filled in, even though I've stuck half an essay in

I know I'm really getting to be all your best friends now, aren't I?
