Set Selection

[dtrots]

I am trying to pick out the third and fourth number from a serial number. I know I can use 'set selection' but can only seem to copy and past with that. Is there something I'm missing to enter numbers from the middle of a field into a variable for a calculation?

I don't see how Set Selection would be useful here. I think you want something like:

Set Variable [ $xyz ; ]

The details of the calculation depend on what exactly does "the third and fourth number from a serial number" mean (from left? from right? how many characters are there? any non-numeric characters? etc. ).

OK - 3rd and 4th from the left - the serial number is always a combo of letters and numbers. Total number varies

So, assuming you want the 3rd and 4th characters (not necessarily digits) from the left, use:

Middle ( SerialNumber ; 3 ; 2 )

as your calculation.
