VLookup function for Placing set pay amount into column by using 4 criterias

I am attempting to put a set amount $ into a column that differs amounts based on type of employee "FT" or "PT". Based on Positions, "A", "B", "C", with value A set to X2, etc - X4. Null for "PT"

I have tweaked it many ways, and have tried the IF nested as well, but the IF nested tells me that I have too many arguments. So I was going with the array and index. I'm thinking that my error is in the range_lookup, however I am out of ideas.

The following is my formula:
=VLOOKUP("FT",[Pay Grade],X2:X4,FALSE="NE")

I appreciate any suggestions.

Here is what I am working on.

Thank you for your assistance.
