Hi and welcome to the forum.

Pls take few minutes to read the rules of the forum, because:

Your post does not comply with rule 3 of our forum.Use code tags around code. Posting code without them makes your code hard to read and difficult to be copied for testing. Select your code and click the [#] button at the top of the post window (if you are editing an existing post, press Go Advanced to see the [#] button).

When exacly do you want to leave the Do Loop?

This is saying loop until all the conditions are met.

which I think is supposed to deal with the problem of an infinite loop, but all it does is put 'diverges' in a cell.

If you want to exit the loop if counter exceeds maxItteration perhaps you should add Exit Do before the End If.
