Scroll Frame Help

[neostorm]

Anyone know a good way to have a scroll frame i've been stuck at this hurdle in my project for some time now. With this limit in the Designer i've considered having a file i edit manually and never open in the editor again after it's set up.

My last attemped involved useing a .lua and creating a .xml file Not a Form. The issues i'm having now is being able to call functions from outside of the .script file.

EX:

MyModData = {};

function MyMod_OnLoad()
  for i=1,50 do
    MyModData[i] = "Test "..math.random(100)
  end
    --Esc Close Option
    tinsert(UISpecialFrames,this:GetName());

    MyModScrollBar:Show();
end

function MyModScrollBar_Update()
    DEFAULT_CHAT_FRAME:AddMessage("UpdateCalled");
  local line; -- 1 through 5 of our window to scroll
  local lineplusoffset; -- an index into our data calculated from the scroll offset
  FauxScrollFrame_Update(MyModScrollBar,50,5,16);
  for line=1,5 do
    lineplusoffset = line + FauxScrollFrame_GetOffset(MyModScrollBar);
    if lineplusoffset < 50 then
      getglobal("MyModEntry"..line.."_Text"):SetText(MyModData[lineplusoffset]);
      getglobal("MyModEntry"..line):Show();
    else
      getglobal("MyModEntry"..line):Hide();
    end
  end
end

        <Scripts>
          <OnVerticalScroll>
            FauxScrollFrame_OnVerticalScroll(16, MyModScrollBar_Update);
          </OnVerticalScroll>
          <OnShow>
            MyModScrollBar_Update()
          </OnShow>
        </Scripts>

The OnShow works but for some reason the update doesn't work.
And i'm unable to call MyModScrollBar:Show();
from outside of the MyModScrollBar.lua

Any help or tips how i might be able to call these functions correctly?

The first thing I would check is the load order. The files are loaded in the order that they appear in the toc file (which is the same as the Project View of the Project Explorer). So in this case I would put the lua file there before the xml file, so that all your code is preloaded before any calls from within the xml file are done.
