The error you posted does not in any way match your code, but this will not getglobal(this:GetName().."Text"):SetText("Offset"); getglobal(this:GetName().."High"):SetText("12"); getglobal(this:GetName().."Low"):SetText("-12"); this:SetMinMaxValues(-12,12); this:SetValueStep(1); There is no variable named `this` and hasn't been for quite some time. If you mean to be referring to the frame for which the OnLoad is firing, you want to use `self`.
