So I've installed web services, have PHP5 installed. I can query my shopping cart no problem, and can get to my web services basic wsdl url no problem.

I've used the provided PHP 5 SO insert example from the Sage documentation and substituted all of my specifc values yet I cannot get the insert to occur, nor do I get any error feedback other than Error 500 when trying to run in CGI mode.

The Sage Web Services documentation is thin to say the least, and I'm wondering if there's a config step that I've missed? I find it odd in the web.config file it is using mas90.sage.com/ws as its binding namespace, but I've not found anywhere in the documentation that it should be changed.

Any advice folks can give to pinpoint the issue would be appreciated.
