Join party with getusetoption('FriendName')?

[sines]

Hello!

How to make this action work with my useroption?

if $self.party == 0 then
contextmenu("Join Name's Party", "Name") 
end  

"Example"

local Friendname =  getusetoption('FriendName')

if $self.party == 0 then
contextmenu("Join ????????????? Party", friendname) 
end  

Thanks

local charName = getusetoption('FriendName')





foreach creature c "ps" do

	if c.name == charName and c.party == PARTY_INVITED_LEADER then

		if $self.party == 0 then

			contextmenu("Join " .. c.name .. "'s Party", c.name, true) waitping(1, 2)

		end

	end

end
