Hi all,
I was wondering if somebody could help me...
I have a form field which I want to lock down so users can only enter a specific combination
eg. first character is a letter - can be either B,C,W,F,A,H which is followed by seven numbers.
I have got some script which only accepts numbers but I do not know enough about javascript so that I can amend it to accept the leading character.
Thanking you all in advance

Amend and expand the code that's in there checking which character you're on and using an ASCII chart to find the codes for the letters you want to allow in position 1. You could also check for the lower-case values and convert to the upper-case values, if you wanted to.
