Attributes[Button]
{HoldRest,Protected,ReadProtected}
The attribute HoldRest is what is causing the observed behavior. Use this
array = {1, 2, 3, 4, 5};
Row[Button[#, Print[#], ImageSize -> {50, 50}] & /@ array]

=============
I'm pretty new to this...
I'm trying to write a function that will create a variable number of buttons (based on some input) and relate each button to a function call with a unique parameter value. For example:
array = {1, 2, 3, 4, 5};
Column[{Row[
Table[Button[array[[n]], Print[n], ImageSize -> {50, 50}], {n, 1,Length[array], 1}]]}]
Gives me five buttons, labeled 1-5, but each prints 'n' when clicked on.
How would I change this to print the value of n?
My best guess at this point is that there is a scoping issue with n, but I don't have enough Mathematica experience to know how to assign static values...
Thanks
