What t is returning when you're indexing the table WayPointLocs ?

[xTanKx]

here you have more lines:

if ( t ~= "Players" ) then 
                    for i, v in pairs ( WayPointLocs [ t ] ) do 
                        local row = guiGridListAddRow ( source ) 
                        guiGridListSetItemText ( source, row, 1, tostring ( i ), true, true ) 
                        for k, f in pairs ( WayPointLocs [ t ] [ i ] ) do 
                            local row = guiGridListAddRow ( source ) 
                            guiGridListSetItemText ( source, row, 1, tostring ( f [ 1 ] ), false, false ) 
                            guiGridListSetItemData ( source, row, 1, f ) 
                        end 
                    end

I index it in the line 5
