error passed but script doesn't work I think it's broken

Try to pass the data on column 0, instead of 1. Maybe that solves the problem. ? 

-- IN
guiGridListSetItemData(transportGUI.locationgrid, row, 0, Data)
--
-- OUT
local DestinationData = guiGridListGetItemData(transportGUI.locationgrid, selected, 0)

i got this error.

Both lines were already inside of your code, at the correct location (before I replied). You only had to change the column id. I have no idea how you managed to get that error.
