The reason the clinician's signature is not on the PFI form is because there's no date in the Financial Screening Date field, please put the date here and then try again, then the clinician's signature should be populated into the PFI.
Also, another reason this can occur, is if the employee signature in their Exym user record has a date AFTER the client's Financial Screening date.
Please make sure that the staff signature on the user file is BEFORE the Financial Screening Date, this means that the staff was employed before the client was there, so they can complete the PFI and the signature will populate.
