Facing Problem while fitting

Hi, I drew a histogram by converting an Ascii file into root format. Now i have to fit the peaks in the histogram. I try to fit only two peaks from the histogram and only one of them is fitted quite nicely. Why the other peak is not fitted properly? Have a nice day.fithisto.C (776 Bytes) [fithisto] !
