Your SQL looks legal (at least for MySQL). Probably a PHP error then.
Do a die( $query )  to see if the query is well-formed and $thisID correctly

Personnally I would rather write:
    UPDATE Choice
    SET         visits = visits + 1
    WHERE ID = {$thisID}
; "
[if ID is of numeric type]

Subject: [PHP-DB] adding integer to field in query

How do you add a number to a field within the query, ie without having to
extract?  Eg

$query="UPDATE Choice SET visits=(visits+1) WHERE ID='$thisID'";

is the above "visits=(visits+1)" legal, cos it doesn't work at the moment?
