CTF uploaded to S2S website gives the following error:
The file does not appear to be a valid 10, 11 or 12 CTF file, please contact your school MIS vendor.
The error is generated because there are incorrect addresses included in the CTF file -e.g. there is text is the street number field or numbers in the street field.
To correct this run the Tidy and Merge Address routine from Tools / Housekeeping. The report should identify any addresses like this which the school can either correct manually, or press the Tidy button in the routine to make the changes suggested in the report.
Schools will need to read the report carefully before they press the Tidy button as once the changes are made, they cannot be reversed.
