Error when calling report in a form

We were using form 6i before and now we use 10gWe have a piece of code like:
Run_Product(REPORTS, 'GRAYS_EMAIL_STATEMENT', SYNCHRONOUS, RUNTIME, FILESYSTEM, pl_id, NULL);

But when I run and execute the form I have an error where it says that run_product(REPORTS) is not supported but we have to use run_Report_Object.
Could some one help please
