URL parameters: By default, when you run a form from Forms Builder, the parameters that are passed in the URL are hidden. For testing purposes, if you want to be able to see these parameters, such as the form name, you can set FORMS90_HIDE_OBR_PARAMS to FALSE (the default is TRUE) . OBR stands for one button run, a term used for running a form from within Forms Builder by clicking the Run Form button.
