Error in ligand

For my ligand PDB file, I get the error message “Second pdb file contains multiple residues with number 0 in chain”.

The pdb file is set as one residue (0) but I´ve tried changing the residue number. I think the problem is within the third columns (HETATM annotation) because all carbons are annotated the same. Am I correct in that assumption and how would I in that case fix it?

Yes all atom names must be unique.

Okey, thank you for answer.
