Crystal Reports Find similarities between two fields

Message

     Is there a formula or something to find similarities between 2 fields. 

Example: I know in field A and B there is the below information in them.

Field A   
AB

Field B
3.2 AB

I linked the two fields above the results I'm getting at the moment is:

Field A          Field B
AB            

I tried using the "like" formula:    If Field A like "*Field B*" then Field B else "", but the result is blank.

What I would like is, if there is a similarity between fields A / B it will display field B.

I hope this explanation is clear.

Thanks in advance.

Steve.
