GRAMMAR Question

<p>In a sentence spot the error question or anyquestion for that matter</p>

<p>when it states blahblahblah, however, blahblahblah</p>

<p>that ",However" is grammatically incorrect right?
It should be a ".However" or a ";however"</p>

<p>but how come on the ACT you are allowed to use a ",however" as an answer? I am confused.</p>
