in the sheet ,
a cell with formula =SUM(ABS(E88:E116)) see the function1.png
another cell with formula =SUM(E88:E116) see the function2.png
between E88 and E116 ,I only enter the E113 with value 34, the E114 with value -30
the problem is :
the result of formula =SUM(ABS(E88:E116)) aways equal to E88, how to solve this? or am I using wrong fomula??
