Count a formula If other formulas are True

Greetings!

I'm trying to count a formula but only if any of three other formulas are True.

Something like this:

If {@Exam 2 - MRI} = True

OR {@Exam 2 - CT} = True

OR {@Exam 2 - OTHER} = True

Then Count ({@Modality 2 - Upper})

The content of ALL of these formulas end with "then 1" so that I can Sum then at the end of the report.  Do I need to change the other formulas so they don't end with "then 1"?  If so, I need to be sure I can still count these other formulas as well

Thank you in advance!!!
