[PHP] problem transferring a variable using POST

[Davy Campano]

I am having a problem with a form.  I am trying to have a form pass a
variable so that I can update an item.  I think the problem is that the
variable (ticketed) is being read as text instead of a number.  These
are the tests I have run.  
 
This statement works:
$sql = 'UPDATE wo SET status = 1 WHERE ticket = 1'
 
This statement does not:
$sql = 'UPDATE wo SET status = 1 WHERE ticket =
$HTTP_POST_VARS[ticketed]'
 
Any suggestions...
 
If I do "echo "$HTTP_POST_VARS[ticketed]"; 
It returns a 1
