vb.net UpdatePanel/Functions

I'm having trouble with codebehind functions and update panels. When i click then "Finish Pallet" Button i want it to run through 3 functions. When each function runs i need some label text to change and some divs to show and hide (my div have runat="server" in them). All three Functions work like they should but they run right through till the last function and only shows the changes of the last function. What am i missing??

Thanks In Advanced!!
