if function returning 0 when it should not

My formula is:

=IF(SUM($E$7:$G$7)=0,HLOOKUP(LARGE($B7:$D7,1),$B7:$D7,1,FALSE),"sweet")

I can't figure out why the above formula keeps returning a zero. Shouldn't it return the HLOOKUP value? I used the "Evaluate Formula" Excel feature, and everything looks good, up to the point of getting a "0," i.e., =IF(TRUE,94,"sweet"). I even pulled the HLOOKUP function out of the formula to test it, and it worked properly. I mean, shouldn't it return the value "94," instead of "0"?

What am I doing wrong?

Thanks in advance,
