Hi! I am facing an error regarding a reference, I have created a report, and the report is displayed on the Tryton app correctly with no error of compilation, but when I open the report it shows an error, “health\_proc.patient\_demographic\_details\_report\_start\_form not found” but I am sure that the form reference is correct. see below for complete information. ![1](https://discuss-cdn.tryton.org/uploads/default/original/2X/8/8ff5bfa32aa46e8151dbfb8469beed5a58274789.png) ![2](https://discuss-cdn.tryton.org/uploads/default/original/2X/b/b9da81496598d3eb421ee7afd287efa1473c987b.png) ![3](https://discuss-cdn.tryton.org/uploads/default/original/2X/5/5d7b4838a6486b1de8345c2540161f2666188af8.png) ---

Hi, do you have in module `health_proc` the following file: `view/patient_demographic_details_report_start_form.xml`? ---
