Hi SDPhantom and AmadiDooke

Yes, I have already tried expanding the edit box and adjusting the insets, all without success.
When I try a test of just the edit box using the following code it works perfectly;

local TestScaleNumber = 123
 
local function updateTextBoxNumber(scaleNumber)
   if scaleNumber >= 301 then -- if the entered number is too high
      scaleNumber = 300
   elseif scaleNumber <= 49 then -- if the entered number is too low
      scaleNumber = 50
   end
   TestScaleNumber = scaleNumber / 100
   TestScaleBox:SetText(scaleNumber)   
end
 
local TestScaleBox =
CreateFrame("EditBox", "TestScaleBox", UIParent, "ChatConfigBoxTemplate")
TestScaleBox:SetPoint("CENTER")
TestScaleBox:SetFontObject(NumberFontNormalLargeYellow)
TestScaleBox:SetNumeric(true)
TestScaleBox:SetSize(40, 25)
TestScaleBox:SetMaxLetters(3)
TestScaleBox:SetAutoFocus()
TestScaleBox:SetText("")
TestScaleBox:SetJustifyH("CENTER")
TestScaleBox:SetScript(
   "OnEnterPressed",
   function(self)
      scaleNumber = tonumber(TestScaleBox:GetText())
      print(scaleNumber) -- debug --
      self:ClearFocus()
      updateTextBoxNumber(scaleNumber)
   end
)
 
updateTextBoxNumber(TestScaleNumber)

This code uses the same edit box code and the same function code, other than the UIParent.
