index of an array

Hi Everyone,
I am trying to get the first index into this two dimensional array, that is 5.

%4 = getelementptr inbounds [10 x [20 x i32]]* %3, i32 0, i32 5

I can iterate over the GEP and get the types of the operands but not the values.

How do I go about getting the value (5)?
Thanks.

George
