How to change the number of decimal places in a variable cell reference...

I feel like an idiot for not being able to figure this out. I want to change the number of decimal places to 2 for a few cell references. My code:

Round(Range("B:" & (q + 2)).Value, 2)

It's telling me it expects an = sign. What am I doing wrong?

Considering the complexity of my macro I can't even figure out something as simple as this.

Thanks for your help!
