How can I remove leading zeros?



Hello,

I have a field with values "AAAA", "0AAA", "00AA", and "000A". I want to
remove leading zeros on the ones with leading zeros. For example, "0AAA"
will turn into "AAA".

Can someone help me with the formula? I have tried using "Val" and "Str",
and they don't seem to work.

Thanks.
