Seems to be a scope issue. Use Delegate (mx.utils.Delegate) to fix that :
allSenators_btn.onRelease = Delegate.create(this, colorAllStates);
This will call the colorAllStates function in the right scope, not in
the scope of your button (or more precisely in the scope of onRelease),
wich it is doing in the code you have now.
Make a search on Delegate in the list Archives and you'll have plenty of
more detailed explanations on what it does.

By the way, here's a picture of this.

The map with colors is when all the code is inside the OnLoadCongress
function. But when I create buttons I get nothin'. Seems that the
numPeople
variable is accessible to the colorAllStates function. But the array
of XML
nodes (Senators) isn't.
Insight welcome!

When the whole coloring routine is inside the OnLoadCongress

can't see
the data.
When I add "_global." before the people:Array declaration I get an error
message.
As in, this yields an error:
var _global.people:Array = XPathAPI.selectNodeList(this.firstChild,
"/people/[EMAIL PROTECTED]'Sen.']");
(Also, can't figure out where "ff" is coming from (when this runs
successfully inside the aOnLoadCongress function, but that's another
question.) Seems if I'm setting things to "ff0000" and "0000ff" that
nothing
should turn out to be "ff."
FYI: The data source on this is a subset of
"people.xml<http://www.govtrack.us/data/us/110/repstats/people.xml>"
from here:

//I want to color every senator on the various committees,

// For now I'm just doing coloring by party.
// Red = Two Republican Senators
// Blue = Two Democratic Senators
// Purple = one of each
// How do I get the XML to be accessible by the allSenators_btn?
// Just slapping "_global." before the people:Array declaration
