Formula to check if string is empty in Crystal Reports

Question

I have written a formula to return a string based on logic run on a string field in my database   I have everything working  except I m unable to return when the field is the empty string   This is what I need       else if   TABLE FIELD        then      Fixed        However  this entry appears as the empty string in my report   I ve tried testing the length of the field to 0 and the StrCmp functions   Nothing seems to work   Google results state that a simple comparison to    or    should make the logic work   I am new to CR  so maybe I am missing something   Any ideas on how I can acquire this functionality
