Julie -
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.
