Summation of array elements

[coolazice]

Hi, I am looking for help with writing a small custom code to sum some elements (about 25 to 35 elements) of an array with 100 elements.

I tried the following code but it did not work and I don't know what else to do.
for (int iArray = ArraySize(array) - 1; iArray >= 0; iArray--) summation += array[iArray];

The only other choice I have is to sum them manually, that is, sum=var1+var2+...var35. This will work but is clumsy and I can only modify the calculation manually.

Please help, thanks.
