Multiple condition formula

I hope the title is appropriate though It doesn't fully express what I need. I need a formula that is basically an IF OR UNLESS statement. When you type that into Google it has nothing to do with Excel.

The formula below says is that if G40 = any of the following then the cell should fill with "Not Changed" but if P40 is less than Q1 which is a Gross profit percentage then subtract S40 from E40 and populate the cell with the answer. E40 = a billing rate and S40 is that billing rate times Q1. The formula is either calculating a new pay rate for me or not changing the old rate and placing "Not Changed" in the field. The problem now is that I also need the formula to take into consideration another job title (Column G) + a company name (Column M) and instead of using the percentage used in Q1 use a percentage in R1.

Is this even possible. Please let me know if this is not understood.

=IF(OR(G40="Behavioral Specialist Consult",G40="Mobile Therapist",G40="Lead Clinician",G40="Licensed Clinician/New Jersey",G40="Psychologist / Psychiatrist",G40="Non Licensed Clinician",G40="Counselor"),"Not Changed",IF(P40<$Q$1,E40-S40,"Not Changed"))

THANK YOU TO ALL OF YOU WHO ARE TEACHING ME!

need to see a sample with results you expect

You forgot to include samples of your expected results, enough of them to demonstrate all the various hurdles. Obviously this would be manual, we'll try to help with the formula version.

In Q3, this adds in the new level test, but you didn't explain the new pay rate, so I marked it for you to enter that formula...

=IF(ISNUMBER(MATCH(G3,{"B","C","LC","LN","M","NLC","PP"},0)),"Not Changed",IF(P3<$Q$1,IF(ISNUMBER(MATCH(M3,{"C","EW"},0)),"New Rate based on R1",E3-S3),"Not Changed"))
