cfqueryparam inside a cfif

I cannot say it is invulnerable to _any_ attacks, but #2 seems like a reasonable approach. It does not use any of the user supplied values directly in the sql. That and the fact that you have set up a default "cfelse" case to handle any attempts to pass invalid values. Though personally I prefer switch/case myself. But that is just me.

If your value has decimal places, then CF_SQL_INTEGER is probably the wrong data type.

BTW, you do not need the extra # signs.

As an aside
1) The default <cfelse> case is missing. So the query would fail if the value was something other than "on" or "".
2) Evaluate is probably unnecessary. You can use array notation to reference dynamic variable names:

#FORM["hidden_"& counter]#
