After the question mark I would like to put information to be included on the page. What I don't know how to do is to separate the information after the ?
I want to create 4 variables from the information:
First 12 letters - file name
Next 2 numbers - length in minutes
Next 2 numbers - length in seconds
Any text after that - song name
For the final bit of text I would like to include spaces in it. I assume I can do this by replacing one character (eg +) with a space but how do I do that?
