GMAT Sentence Correction (SC) | Re: At issue in the proceeding is whether the gaming firm

Hi guys,

I was unable to comprehend the meaning of the sentence. As per the sentence, the gaming firm verifies 2 things:-
1)the site’s users are over 21
2) in a legal gambling state or country - This is where I am having problem.

How can one say gaming firm verifies in a legal gambling state or country. Shouldn't it be the gaming firm verifies the site’s users are over 21 in a legal gambling state or country.
The use of and makes the meaning weird.

Please tell me where I have mistaken.
