Job Description

I need assistance with developing several formulas for a crystal report. The first formula is creating a sum function on distinct values. Similar to distinct count but for the sum function.

The second formula is creating a balance based off of the value being subtracted from the opening balance.

I then need the ending balance formula.

I need this today so only apply if you can deliver today.
