Formula Tool Incorrectly identifying text

[HW1]

I have a formula tool with the formula:

IF Contains("Services / Site", [Value]) 
THEN "Services" 
ELSE Null()
ENDIF

It does not identify the text correctly.

Please find the attached workflow for an example

Why is it happening?

Hi @HW1 

At first glance it looks like you have the contains function backwards. The syntax is contains([Field], string you want to find in the field)

Right! Silly me 🙂 Thanks
