Defra doesn't recognise that recovery or disposal code

Defra reads R1 to R13 and D1 to D15, in capitals, and this code did not match.

What to do

1. Press Correct the record.
2. Pick the treatment code from the list in Tipslip.
3. Press Save correction and re-submit.

Tipslip sends the corrected record to Defra as soon as you save.
