Triplesubmit form problem

Hi!

I have this form at:
URL

This is to calculate stats and modifiers for my game system. However, when stuff is entered, it has to be submited three times to get correct information.

The code is unfortunatly fairly long but I assume this is a fairly simple issue caused by my lack of knowledge.

If code sample is needed, I have made it available at:
URL

Any help would be appreciated!

future point of interest, saving the file as phps displays the code in a color-coded format... simply rename the file to contain a phps file extension...

i'm working on reviewing the code, i'll see if i come up with something.
