"menuf4" isn't a valid classname for a derma panel unless you've created it on your own hence it will be nil when MEF4:SetVisible( false ) is run.

thanks will try and give it a new name

[LegendarySoldier]

That's not for naming it, you pick the derma element. It needs to be one of these VGUI Element List
