using Codeigniter (and Grocery Crud) in phpStorm

I am using phpStorm and CI and  Grocery CRUD. From the address bar in Chrome I can get the CRUD example page to run by typing localhost/crud_example/index.php/examples. I can also get the CI welcome page to work. Works great. I want to develop and debug under phpStorm but I cant seem to get it to run within phpStorm. I have modified the command line like in the screenshot but I get "config error". Should I use the built in web server rather than XAMPP? I am heavily dependant on a debugger when coding. Are there instructions anywhere for using CI in phpStorm. I saw the auto complete add in. Autocomplete is not super important to me though.
