I just cant find how i can test of my cell got follwing format:

AAA-000

A= A character
0= A number

if the format is like jonas-154 he must give a false back in a if statement because it must be jon-154
or when it is 145-478 it must give error beceaus it must be chacters and then -
and also i want something that test if there is more than one - in a cell

pleas react fast need it fast

thx jonas "Spykie" verhaert
