Alright guys.

I need a little help about this argument, so whenever it renders, warnings apppear

y1 and y2 are nill

  
    function clicked () 
   if source == rulesb then 
         guiSetText (helpmemo, rules) 
        y1 =(158/ry)*sy 
        y2 = (189/ry)*sy 
    elseif source == Infob then 
        y1 = (199/ry)*sy 
        y2 = (230/ry)*sy 
          guiSetText (helpmemo, commands) 
    elseif source == rosterb then 
        y1 = (240/ry)*sy 
        y2 = (271/ry)*sy 
         guiSetText (helpmemo, info) 
    elseif source == commandb then 
        y1 = (281/ry)*sy 
        y2 = (312/ry)*sy 
         guiSetText (helpmemo, admins) 
       end 
end 
addEventHandler("onClientGUIClick", root, clicked) 
  
function fill () 
    if (isOpen) then 
        dxDrawRectangle((211/rx)*sx, (158/ry)*sy, (157/rx)*sx, (31/ry)*sy, tocolor(107, 87, 171, 185), true) 
        dxDrawLine((367/rx)*sx, y1, (367/rx)*sx, y2, tocolor(255, 255, 255, 255), 2, true) 
end 
addEventHandler("onClientRender", root, fill) 

how do I solve it?

You must declare those values before anything else. And if possible, set them a default value. This line at the beginning of the script should do the trick:

y1,y2 = 0,0 

Unless you're not posting something relevant here.
