The syntax for the if() statement is:
IF(CONDITION, TRUE_VALUE, FALSE_VALUE)
CONDITION is the expression you want to evaluate.
TRUE_VALUE is the value the function returns if the CONDITION is true.
FALSE_VALUE is the value that is returned if the CONDITION is not true.
If you separate your logic into separate rows, it will be easier to see
If your CONDITION is true, then the TRUE_VALUE will always return "TRUE", and you hardcoded the FALSE_VALUE to "True"
