Hi there,

I am trying to extract a form field into a variable within the same form for
the purpose of generating a unique tracking number. The user makes a choice
from a drop down menu, and two letters that relate to this choice are
inserted into the PHP generated number.

I have tried to set this variable using $_POST but it doesn't work, (I
assume because when submit is clicked it can't access the $_POST result?)

Can anybody tell me how to achieve this?

Thanks,

Nick.
