validating a field

Hi,

I was trying to validate a field for the past two days now, but I can't get it to work. So if anyone here can help me, I'd be really thankfull.

It's about a field containing 4 digits and 2 letters, like this: 1234AB. I can't seem to get it done. The closest I was was a script that checked if the first item was a digit, and then the second, and then the third, end the fourth. After that it checked if the fifth was a letter, and after that the sixth. After more than two screens of 'ifs' it didn't work :(

Thanks in advance
