Hi All,

I hate posting without at least having a starting point but I am
absolutely clueless on this one. When a user enters an eleven or
thirteen digit number into the subject I would like to do some
processing on it.

We use a barcode scanner to enter an eleven digit number into the
subject line which is then manually reformatted to remove the last
digit (a check digit) and add a hyphen between the sixth and seventh
digits. I would like to automate this so that as soon as the value is
entered (onKeyUp event???) it is reformatted programmatically but I am
struggling to say the least.

I will be very grateful for any pointers given.

TIA

Nick
