problems with hide show command

[seres]

hello, this is my code

HotKeySet("#+s", "hsseres")

func hsseres()

if WinExists("seres") then

WinSetState("seres", "", @SW_HIDE)

Else

WinSetState("seres", "", @SW_SHOW)

endif

EndFunc

when i click in the combination it hides it but when i click again it doesnt show the window that i have closed.

i think its cause of the window seres still exist even if is hidden i tried if winactive then but the window has to be active to get closed ,

can someone help me so it closes and opens with one key combination

Instead of WinExists use WinGetState
