This example creates a player list on resource start, clicking on it will output the selected player name to the chatbox. 

function clientsideResourceStart ()
    local numberList = guiCreateGridList ( 0.80, 0.10, 0.15, 0.60, true ) --Create a gridlist
    local columnA = guiGridListAddColumn ( numberList, "columnA Title", 0.85 ) --Create a columnA on the gridlist
    rowA = guiGridListAddRow ( numberList )
    rowB = guiGridListAddRow ( numberList ) --Add 2 rows to the grid list
    guiGridListSetItemText ( numberList, rowA, columnA, "Hello", false, false ) 
    --Create the text "Hello" for rowA, columnA
    guiGridListSetItemText ( numberList, rowB, columnA, "World!", false, false ) 
    --Create the text "World!" for rowB, columnA
	getRandomItem = math.random ( 1, 2 )
	if getRandomItem == 1 then --Choose randomly which grid list item text to retrieve
    	        randomItemData = guiGridListGetItemText ( numberList, rowA, columnA )
	elseif getRandomItem == 2 then
		randomItemData = guiGridListGetItemText ( numberList, rowB, columnA )
	end
