Sorry, but at the 3rd level, you have to run one contrast at a time.
There was a thread on this in the list not too long ago.

I ran the lower level analysis so now each subject has 7 FEAT folders (1 for each run). At the second level, I selected higher level analysis and combined the 7 runs for each subject. Now each subject has 1 gfeat folder. Both the 1st and 2nd levels were run at fixed effects. Now on 3rd level (group analysis), I want to compare subjects from group A vs group B. To do this, I selected higher level analysis and picked the input are lower level gfeat directories from the 2nd level analysis. However, FEAT was not able to detect stat/cope images. It did work though if I selected the cope feat directories, but this requires me to run each contrast individually.
