You can use the function instr to check for the string.

Instr is good for quick solutions, if your strins is BIG or you have to use thisoften you are better off met converting the string to an array an dthen use filter to find teh value

so

dim temp, aTemp
temp="alpha,bravo,charlie" 
aTemp = split(temp,",")
aFound = Filter(aTemp , "alpha") ' aFound (0) contains "alpha" or is an empty array if not found.
