You have an extra end) at the end of the code block. I assume that's line 127, right? That is, unless this code is inside a block that starts somewhere we can't see in your except.
Be sure to be careful with identation when writing function blocks! It helps to make sure your function() blocks are properly closed with a corresponding end.
One extra thing. This:
dPanelButton1.Paint = function( self, w, h )
...
end
Can instead be written as:
function dPanelButton1:Paint( w, h )
-- the 'self' arg can be omitted by using colons ":" instead of dot "." during declaration and calls.
-- this is the most common way of passing the table the function is stored in as the first argument, implicitly named `self`.
-- In other words, calling `dPanelButton1:Paint(1, 2)` is the same as calling `dPanelButton1.Paint(dPanelButton1, 1, 2)`
...
end
And this:
dPanelButton1.DoClick = function()
...
end
Could be written as:
function dPanelButton1.DoClick()
-- Writing `function foo(arg)` is the same as writing `foo = function(arg)`.
...
end
This makes the function blocks clearer in the code and is easier for others to read. Clean readable code is how you prevent syntax errors (well, that and an IDE).
