Hi Guys ,

I Have a DATA based on the grid according to the values which will be put
ting

Like if A = 0 AND U = 1 I Want the marks to be shows as 1

but if the A=1 And U = 1 I want the marks to be shown as 0

And if A = 2 AND U = 2 I want the marks to be shown according to grid

and if A=2 And U = 1 I want the marks to be shown as -2

i Tried one formula but i m not satisfied with the result plus also i dont want

value to be shown as 2 if no values are entered in A or U
