Does anyone know if there is a way to use the if function to search for comma's within a cell. For instance, in the below, using the if function, I've tried the below without success.

if(A1=",","Flag","Unflag")

It's obviously wrong...I'd greatly appreciate if someone can lend me a hand. Seems simple enough but can't figure it out.
