Thanks for allowing me to post the problem. Finished teh post and searched
one more time, came up with teh ISERR and applied that. Worked great! here is
what I finally used
=IF(ISERR(RIGHT(A61,(LEN(A61)-FIND(",",A61)-1))&"
"&LEFT(A61,FIND(",",A61)-1)),A61,RIGHT(A61,(LEN(A61)-FIND(",",A61)-1))&"
"&LEFT(A61,FIND(",",A61)-1))

Where Col A contained a combination of "fname lname" and "lname, fname"
entries.
Maybe this will help someone else down the road!

Inherited a spreadsheet from another user. Have a mixture of lname, fname
and fname lname combinations. I can successfully convert the lname, fname to
fname lname, teh problem is those cells that are already in the fname lname
return a #Value error.

I thought I could find a way to logically test the string for a comma(,) and
use an If statement to control my concatenate formula. I can't find a way to
test logically for the comma.

Can anyone offer a solution?

Thank you
