What happens if 2/3 of the Senate votes to convict an impeached president but not on the same charge

[Sir Mohamed]

Would be acquitted then. Prez needs to be convicted in one charge with 2/3 majority reached.

A proposed bill also doesn't pass if more than one version is voted on but neither reaches a majority on the floor, even if "combined yes" votes on 2 or more versions is a majority. The chamber needs to agree on one version and pass it with a majority vote. Just like impeachment needs  a 2/3 majority on at least one charge.
