How do I make a shop with array?

Hi guys, i make a clicker-game and i dont know hot to make a shop with array, can you help me?

P.S. sorry for my English, im from Belarus.

You create an array like:

["item1","item2","item3","item4","item5","item6","item7","item8","item9"]

then,

for "index" 0 to 8

TextObject: append text "array.At(loopindex) & newline"
