Are Projected Costs and Actual Costs more custom fields? If so, you need to set the summary tasks to roll up. In the customize field dialog, select to either sum, min or max. But I have to ask - why all the custom calculations? If you save a baseline you'll have "projected costs" in baseline cost. If you apply tracking - you'll have actual costs.

I did set the summary tasks to roll up - but I still receive errors. I used custom fields with formulas because I downloaded MS Project at work and I just wanted a simple project that showed me a simple timeline with lost time and money. Sofar I have that, all except the rollups. Still not sure why the sub tasks only roll up to one summary task. I also tried setting the baseline like you said, but it didn't change anything as far as the rollup.
