making my data more concise

I have a large spreadsheet of data, with various columns with different bank names, the amount (column H) each bank holds plus loads of other columns. Some of the banks are duplicated, so in a way I want to do an advanced filter to get rid off the duplicate lines, except that I need the amounts (column H) summed.

Tks!

Pivot table. http://office.microsoft.com/en-us/ex...346321033.aspx is among many web resources.
