[rules-users] Help writing rules

Hi I’m having a little problem in writing rules for my expert system. I know that this is probably written out very badly and I really don’t have much of an idea on what I’m doing in drools but I’m trying to get the following rule to run Rule "test body button check" when (Bodyc(brownb == "true") || Bodyc(grayb == "true") || Bodyc(lightgrayb == "true") || Bodyc(redb == "true") || Bodyc(orangeb == "true") || Bodyc(yellowb == "true") || Bodyc(whiteb == "true")) && (Bodyc(blackb == "false") || Bodyc(greenb == "false") || Bodyc(blueb == "false") || Bodyc(cyanb == "false") || Bodyc(pinkb == "false")) then System.out.println("body check pass"); end if I remove the double and symbols in the middle plus everything after the rule does run. basically I need the first half of the rule to evaluate true and the second half to evaluate false but in the same rule. Any help would be greatly appreciated.
