Hi all, I have three inputs required at a prompt in the index file below which requires the following data a number which will be the title code such as tt0892318 and a number that will be prefixed with tt and be interpreted as the title code such as 0892318 and http://www.imdb.com/title/tt0892318. The problem I have is that the 0892318 is always returned as an empty string. Test have shown that the split string function is working and sends the correct data but returns empty.
If anyone can assist with this I would appreciate it.
Thanks in advance
David
