I don't understand how I could use > DynamicModule to do this, but what other options do I have. there was another post just today which asks exactly the same thing, so you might want to check that thread for solutions, too. Here is a short answer: Manipulate[ parameter1 = n; Plot[Sin[n x], {x, 0, 2 \[Pi]}, Frame -> True, ImageSize -> 400] , {n, 0, 1} ] you can just set a global variable within the Manipulate body and use that in the rest of the notebook... hth, albert
