Thanks acer! 

Unfortunately, Maple 12 is my go to version.  15 is not readily available for me and with 15 being the go to versions of choice for many users now, I'll probably be hardpressed to get many users to bother tackling the problem.  At least I know it works in 15.

I understand that a lot of improvements/enhancements were done to the HTTP package since 12 and that was probably one of them.  If it is a bug, I might be stuck.  Usually a workaround exists ... hopefully?

@Robert Israel just to confirm it works I had access to Maple 15 but for users of Maple 12 there is a subs bug that doesn't allow the substitution.

We could circumvent the issue Maple is having with a small proc so we don't have to keep redefining the graph

DrawGraph2 := proc (G, p) #specific to tree style structures
  uses GraphTheory:
  DrawGraph(Graph(undirected, G), style = tree, root = p)
end proc:

DrawGraph2({{2, 3}, {2, 4}, {3, 5}}, 3)

            3
         /     \
       2       5

      4

It must be the internet connection program I use that doesn't support the operations.

Not exactly sure what you mean.

Actually I don't thinik that is what you want, you could try DrawGraph from the GraphTheory package.

Here's my reason.  I was in Typesetting:extended mode.  In your example %A doesn't work with typesetting set to extended but %a does.  That was before I found the bug in extended mode for coloring.  Then I posted the typesetting extended bug and this morning saw your message that you meant %A not %a.  So I tried it again and %A didn't work so .. I thought maybe typesetting is the problem, so I checked to see if it had an effect and in fact it does.

I think you meant to write
nprintf("#mo(%a,mathcolor=\"%A\")", s, c)

The first `a` being lower case instead of upper case.
