Extract last two numbers from Token

Hi all,

New to expressions,  not sure why this isn't fully working.

 

I'm trying to extract the last 2 or 1 numbers from a string. It seems to work if there are 2 numbers but not 1?

 

Any help appreciated.

 

Thanks

Your expression is implicit that it is looking for 2 digits at the end.

You can make the expression more flexible by using \d{1,2}$

- this means the it is looking for 1 or 2 digits at the end of the string

or \d?\d$

- the ? means Optional, so it says it's looking for 1 digit at the end with an option for a digit in front of it.
