Round Statement Incorrect Value

Hello,

I am having trouble getting the correct calculation with the statement below. The error is that QTR4 is being divided by Select SUM instead of all 4 quarters. I have tried closing the addition statements but get errors on all scenarios that Ive tried. How can I format this to correctly to add up all 4 quarters then do the division?

SELECT campus.campus,
ROUND(QTR1+QTR2+QTR3+QTR4/(SELECT SUM(QTR1+qtr2+qtr3+qtr4) FROM campus),2) "% CONT"
FROM campus;

CAMPUS % CONT
-- ----
Main 1300.16
East 700.08
West 300.04
North 350.04What do you mean by "closing the addition statement". Shouldn't you to put parenthesis over QTR1+QTR2+QTR3+QTR4 ?

SELECT campus.campus,
ROUND((QTR1+QTR2+QTR3+QTR4)/(SELECT SUM(QTR1+qtr2+qtr3+qtr4) FROM campus),2) "% CONT"
FROM campus;
