I can give an answer to my own question. By dumping Manipulate and using Dynamic instead I get: n == 5; x == Table[RandomReal[], {20}]; Column[{ Row[{Slider[Dynamic[n], {1, 10, 1}], Dynamic[n]}], Dynamic[Column[Table[With[{i == i}, Row[{Slider[Dynamic[x[[i]]]], Dynamic[x[[i]]]}] ], {i, n}]]]}] This was taken from the Dynamic tutorial with the outermost DynamicModule stripped off. I had tried for over a week using Manipulate with no progress. Once I gave up it took me just one morning of reading plus a few minutes in Mathematica to get something that works. Hopefully the real problem will go smoothly. ---- Dean On Dec 5, 2010, at 6:56 PM, Dean Shough wrote: > I have a need to nest Manipulates, but using global variables instead of > local variables.
