Help! GUI Bug!

[FlyingSpoon]

For some reason when I enter marker, the GUI pops up. But somehow it appears for all players?

I only want it to appear for me, or when other players enter only for them. Not for everyone?

Can anyone help me thanks!

[Enargy,]

change the argument of the line #60 to #66 for this:

addEventHandler("onClientMarkerHit", root,  
function() 
if isElementWithinMarker(getLocalPlayer(), nMarker) then 
guiSetVisible(mainWin, true) 
showCursor(true) 
end 
end)

function markerHit(hitElement) 
    if hitElement == localPlayer then 
        if source == nMarker then 
            guiSetVisible(mainWin, true) 
            showCursor(true) 
        end 
    end 
end 
addEventHandler("onClientMarkerHit", root, markerHit)
