Hi I need help replacing the xml file. I get errors when I replace the local xmlFile and local dataURL. The error from replacing the xml file are:
detailTitle.x = math.floor(detailImage.width) + detailDate.x + 12
and
–#Load the data
–for k,v in pairs(dataTable[2][1][4][4][‘xarg’]) do print(k,v) end
for i=4, #dataTable[2][1] do
data[i-3] = {}
data[i-3].eventTitleValue = dataTable[2][1][i][1][1] or “”
data[i-3].eventDateValue = dataTable[2][1][i][2][1] or “”
All I’m doing is replacing the xml file with one of my own that has the same structure. Does my dataTable need to be “set up” differently to compensate for the new data? Its a completely different website all together. Thanks.
