summing all values up

how can i sum all values that i got from a loop????

What loop?

How are the values stored? Are they in an array? If so, just write another loop that traverses the array and keeps a running total.

If you got the values in a loop you can either write another loop as sean suggest or just put your "sum" code in the loop where you first process the values. You need to initialize some variable that is going to hold the sum to zero and then in the loop you add the values you want to sum up to this variable to get your running total.
