I am completing a 2012 ITR12 form for a member of a cc which is not registered for PAYE. In the past, I used to disclose this remuneration under "Local Business, Trade and Professional Income", using source code 3535 (Members of CC/Director of a company). When using this source code now, I get an error saying "only numeric digits may be used/ Ensure that the source code falls within the respective ranges". I have called SARS, according to them the code has not changed, it should work. I am getting the same error on other ITR12's, it is not limited to one taxpayer. I have also tried other pc's, thinking it might be the versions of software installed on my pc.

Can someone please help?
