Thank you for the reply, it partly solves my problem, but what if I want to control the length of the array 'vars' as well with a slider? Here is my proposed - not working - layout, based on your code: Remove[vars, a, x, v, n]; {Slider[Dynamic[n], {1, 5, 1}], Dynamic[n]} a = Table[RandomReal[], {n}] vars = Dynamic /@ Array[v, {n}]; x = (Slider[#, ImageSize -> 50] & /@ vars) MapThread[Set[Evaluate[#1[[1]]], #2] &, {vars, a}]; vars Clearly the problem starts when variables 'a' and 'vars' do not update with the change of n. Of course, if I wrap the Table[...] and Array[] expressions into Dynamics, MapThread won't recognize them as lists. Is there any way to define 'n' as an always-dynamic-variable (other than incorporating the whole thing into a Manipulate)? Any ideas? Istvan
