Invoking rest web service from button no parameters

I have a page where I have a button that invokes a web service which works fine however when I try to get it to pass a parameter on the path it does not seem to add it.

I have added the parameter in my data section and I have added the parameter to the invoking in the button event but still no parameter added to my call.

I’m probably missing something obvious …

How is the web service parameter specified? You can send us the meta directory of your application to so we can take a closer look.

Adding the path to the resource worked perfectly. Thanks for the quick solution!
