Editing a post on Facebook

[Chasingcars]

I added a post last week on Facebook but made a small error plus want to tag some people...I want to go back and edit the comment and tag people however when I go to 'edit post' the only options are to amend the location or date...does anyone know how to edit the actual comment and therefore tag someone?
I looked the same question on FB help and it says you can edit post but as I say only seems to give me the option of changing location or date!
thanks in advance

If I want to change a comment due to a spelling mistake I copy the current text into the clipboard...

then paste the text into a new comment, make the changes and save it as a new comment.

then delete the original comment.

Thanks VHG, how about comments from other people already linked to original post - would they dissapear i guess?

If you delete the original comment, then you'll delete everything linked to it: comments, etc.
You could always amend the typo underneath to acknowledge your mistake:

"The sky is bluee."

Amendment: "blue*"

Also, you can comment and type "@", once you've done this begin typing a friend's name without a space and names will appear on a drop-down menu. Select them from there and they're then tagged and linked to the post via the comments.

These solutions aren't ideal, but at least you don't lose your comments. . .
