Incorrect Argument Set: Nested IF Formula with 3 Logic Statements

Question

I have the following formula that works and I would like to add one more criteria, if Bid? = "Bid" then return 100% in %Complete Column

This is the original working formula:

=IF([Include in Estimate]@row = 0, 1, IF(OR(NOT(ISBLANK(Units@row)), NOT(ISBLANK([Fixed Cost]@row))), 0.25, 0))

This is my edit which returns the Incorrect Argument Set

=IF([Include in Estimate]@row = 0, 1, IF(OR(NOT(ISBLANK(Units@row)), NOT(ISBLANK([Fixed Cost]@row))), 0.25, 0), IF([Bid?]@row = "bid", 1))
