Hi Everyone, hopefully someone can help me

Ive made a basic template for serato in touch osc but cant get the pd extended to talk to my ipad or respond to its commands.
do i still need to put in my ipads ip address into the pd file like the basic one shown on the touchosc website?

It would be great if someone could look at the file ive attached and tell me what else i need to put in.

Cheers
