How to input code in type multichoice?

[AjYouTube]

function main()

menu = gg.multiChoice({' demo1 ',' demo2 ',' demo3 ', ' demo4','demo5','demo6'},nil,'demo by aj')

if menu == nil then main() end
if menu[1]  then d1() end
if menu[2]  then d2() end
if menu[3]  then d3() end
if menu[4]  then d4() end
if menu[5]  then d5() end
if menu[6]  then d6() end


end

Use all d1,d2,d3,d4,d5,d6 function before writting the multiChoice

 

If you write after, then it will give error(nil value)

 

First write all function  then write multiChoice
