HI Jenny,
Yes, the payments report is for who is left to pay and how much individually.
For your purpose, you could try:
1. Goto Campaign List, select campaign, the click Campaign Financials. This provides you with the total value, non income, income (the total from your customers) etc.
or
2. Goto Reports, Campaign Income (down the very bottom), enter the campaign no. This report gives you all the figures as well.
Let me know if this is what you are after.
Cheers,
Kerryn
