Issue with Solver

Dear all,

I will try to describe the issue that i have with Solver:

I have random amounts in 2 scenarios and I am trying to find a particular target amount, which is a sum of count (x) of amounts from 2 lists – with 16 and 24 amounts

Now, the solver is working just fine with the 16 amounts, but when trying with 24 amounts, it is not able to find the particular amount I am looking for, but is finding a slightly different result with tolerance and I am searching for this very amount. I am using GRG Nonlinear method without automatic scaling. The variable cell is SUMPRODUCT function of 2 arrays, the first one with the amounts, the other one is "0"

attached is the file with both scenarios

Any help will be greatly appreciated and hope I have explained myself well.
thanks
