SetModel With Bodygroup

Hi! im using these player models
http://steamcommunity.com/sharedfiles/filedetails/?id=204120003
and i was wondering how to set the model on the player with a certain bodygroup?

Would it be like this


ply:SetModel( "example/path" )
ply:SetBodygroup( 1 )

^^ sorted that but i need help now with something else!
how could i change the bodygroup with a NumSlider?

this doesnt work



local NumSlider = vgui.Create( "DNumSlider", Frame )
NumSlider:SetPos( ScreenScale( 360 ), ScreenScale( 50 ) )
NumSlider:SetWide( 250 )
NumSlider:SetText( "Suit Design" )
NumSlider:SetMin( 1 )
NumSlider:SetMax( 14 )
NumSlider:SetDecimals( 0 )
NumSlider.OnValueChanged = function()
	local NumValue = NumSlider:GetValue()
	LocalPlayer():SetBodygroup( 1, NumValue )
end
