GuiTextCtrl - Change Text Dynamically

I've looked over several forum threads and it looks like it should be simple to change the text in a GuiTextControl from a function within a Scirpt file, but I can't get it to work. The following is an exerpt from my code with some extraneious code removed to highlight issue. Can anyone give me a pointer on this issue either from looking at my code or just the method itself?
Thanks,

SCRIPT FILE CRATED WITH JEDIT WHICH HAS FUNCTION TO CHANGE TEXT
// campHUBOfficeBtnCtrl
// Vron Software

// Campaign HUB Office Folder
function displayOfficeFolder(){
echo("Office Folder");

Canvas.pushDialog(campHUBOfficeDialogGui);
}

// return to HUB from Office Folder
function returnFromOfficeFolder(){
closeRosterPg();
closeBldgsPg();
Canvas.popDialog(campHUBOfficeDialogGui);
}

// Office Folder functions
function displayRosterPg(){
// make sure other folder pages are closed
closeBldgsPg();

// set Roster heading to visible
OfficeFldrRosterHeading.visible = "1";
// set Roster names & set to visible
%currentSJ1 = $sjRoster::name[0,1,0];
sjCurentRoster1.text = "Randy Brooks";//$sjRoster::name[0,1,0];
//%currentSJ2 = $sjRoster::name[1,1,0];
sjCurentRoster1.visible = "1";

(SOME CODE REMOVED FOR CLARITY)

offFldrResourcePtsBalTotal.text = 2000; //$pref::Player::ResourcePts; ====== VARIABLE TO CHANGE DYNAMICALLY

Canvas.repaint();
