the marked problem
Error Invalid source /obj/sphere_object1/attribwrangle1/attribvop1 Error: Syntax error, unexpected identifier, expecting ')'. (1,46). Warning Syntax error, unexpected identifier, expecting ')'. (1,46)
is on (sometimes after) the first quantity clamp.
sometimes I had the same problem elsewhere. No Idea whats going on with this code.
