Mobile redirect with Andy Moore php script

Hi - I have older website under html 4.01 transitional, created sub-domain for mobile site, constructed mobile site with jquery mobile, created [login to view URL] file for root directory, placing Andy Moore redirect script header above Doctype. Uploaded new parts of site, the [login to view URL] file, the .htachass file that he provides. Site hosted on Apache and it's set up to handle project. Can't get it to work and need help on the php script file. Thanks
