Set off of loss not allowed

Hi All

I had filed Income Tax return for AY 2010-11 manually. In nutshell, I had declared income as follows

Salary Rs 2406721, House Rent 11878(net of std deduction) Short Term Capital Gains 52135 and Income from Other Sources as 13150 Total Rs 2483884

I had also claimed set off of Brought FOrward Losses of Rs 4000 from Income from House Property and Rs 40000 of Short Term Losses of previous year

Somehow the Income Tax department while making the income tax calculations did not allow me these deductions. Request if any one can suggest me way forward as How to appeal or ask for rectification

Thanks in advance
