Rewrite sentence using commas.

In the June 29 1999 edition of the Mercury there was an article on skateboarding.
I wrote...
In the June 29, 1999 edition of the Mercury, there was an article on skateboarding.

You also need a comma after 1999.

Thank you Ms. Sue, I questioned that. I have a few more.

To rewrite the sentence using commas, you should use them to separate the date "June 29, 1999" from the rest of the sentence. Here's the revised sentence:

"In the June 29, 1999, edition of the Mercury, there was an article on skateboarding."
