Well...

First, you don't need to use the SUM() function at all (that's usually
the sign of an unreformed Lotus 1-2-3 user)

Second, using the IF function requires you at least have a TRUE value
specified (but you don't need the IF() at all).

Third, noting that your condition can only return TRUE if K2 and U2 are
both negative, it can be rewritten:

=AND(K2 < U2 * 0.8, K2 U2 * 1.2)

I have this formula that works in excel.
=IF(AND($K$2(SUM($U$2*0.8)),$K$2<(SUM($U$2*1.2))) ,"true","false")

And when I try to get it as conditional formatting I get the "not enough or
too many parenthesis" error.

This is what I tried in onditional formatting.
=if(and($k$2<(sum($u$2*.8)),$k$2(Sum($u$2*1.2)))) .

What am I doing wrong or can I not us the and function in conditional
formatting?

BTW, this is the 3rd criteria so don't tell me to split it up (the first two
are between functions)
