MrC:
Hint.  Use expression columns to work out the small pieces of your larger functions.  Then, when you have the sub-components working, place them into the larger expression.

IsEqual() tests for equality against some value.

IsEmpty() tests that the field is empty (or sometimes a 0 value).  IsEmpty() would usually be supplied with the raw field value, so that the pretty, human-readable display value isn't being used in the expression.  If you're testing for emptiness, then you wouldn't want to have the expression testing against the string value "Unknown", which is the human-readable version of an empty field (in many cases).

thunderlips222:
This makes more sense to me. So essentially you're creating custom expression tags so that you don't have to create crazy long, complicated formulas.
