Determining absence entitlement using absence reason

Summary:

We have a requirement to determine the entitlement available depending on the absence reason selected e.g, Absence Reason 1 allows a maximum of 7 days but Absence Reason 2 allows a maximum of 5 days. The attached fast formula was created and compiles however once attached to the absence type it is not being acknowledged and users can submit any length of absence.

Has anyone else configured this before and can help?
