yes i entered fixed costs only
and yes i saved a baseline



but ity only calculates against the original baseline, but not the other baselines i might have saved such as baseline 1 2 3 4 etc... correct? because BCWP, which is in other words EV, I saw only one of it, which made me think it is only taking the original baseline into account but not the others....

Earned value is calculated, by default, against the Baseline. You can change which baseline earned value is calculated from through Tools > Options, Calculation tab - earned value button. However, you cannot use different baselines for different tasks.

I hope this helps.
