[Closed] Problem with scripts

im a beginer to scripting in max, my scripts tend to work only once, if i run them twice within the same session of max–even after resetting–i get errors and the errors dont seem to be to be with variable naming, and often Max just crahes when wwriting/running scripts.

one other problem i have is scripting rotating objects. how would i rotate an object a complete revolution ie. a multiple of 360o …any help would be most appreciated, thanks
