The problem is that Print[n] is only evaluated when the button is pressed and then "n" doesn't have a value. In the online help is an example (Button/scope/button control) that shows how to do this Table[With[{i = i}, Button[i, Print[i]]], {i, 5}] Eric On 12 okt, 10:34, SDY <young... at gmail.com> wrote: > I'm pretty new to this... > > I'm trying to write a function that will create a variable number of butt= ons (based on some input) and relate each button to a function call with a = unique parameter value.
