attempt to compare nil witch number

[Thiago04]

is giving this error, just do not know how to tidy and would like help if possible, those are the lines.
 

function isCursorOnElement(x,y,w,h)
 local mx,my = getCursorPosition ()
 local fullx,fully = guiGetScreenSize()
 cursorx,cursory = mx*fullx,my*fully
 if cursorx > x and cursorx < x + w and cursory > y and cursory < y + h then
  return true
 else
  return false
 end
end

check arguments in use your function isCursorOnElement

[AndresTVz]

isCursorHover = function(x,y,width,height)
    local sx,sy = guiGetScreenSize()
    if isCursorShowing() then
        local cX,cY,_,_,_ = getCursorPosition()
        if cX and cY then
            if cX >= x/sx and cX <= (x+width)/sx and cY >= y/sy and cY <= (y+height)/sy then
                return true
            end
        end
    end
    return false
end

If the mouse is within the values that you enter the function, it will return true.
