In the old version of condition doesn’t exist "Contain" function, also [Choice Column] == "value" doesn’t work. The "IndexOf" function can help to solve this issue.
There is a Status column in Task list, that is default Choice Column.
We want the condition trigger a product, when the status is "Not Started".
so the formula is: IndexOf([Status],"Not Started")!= -1
Integer IndexOf(Text s1, Text s2)
Checks for the presence of string s2 insideof string s1. If string s1 does not contain string s2, it will return -1.
