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

Subject: 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?
Thanks,
John
