Thankks tskyyc, That could not be it. the left and right leg of each pair move correctly. It's when the relation between front and back that is the problem (inverse movement).... thx for the help

Dear All, I've just done page 68 of book 2 and the problem arises at step 100. When I want to extend one pair of 'legs' the other pair does the reverse movement. Front legs in => back legs go outwards, and the other way aound; Can somebody please help? thanks,Tom
