That code executes if the value is not equal to "0" or the length is not
equal to 0. Plug "" in and it is not equal to "0" so it executes. Plus "0"
in and the length is not equal to 0 so it executes.
You want
<cfif (variables.choiceValue neq "0") and len(variables.choiceValue)>
...
</cfif>
You might find the condition easier to write as:
<cfif (variables.choiceValue eq "0") or (len(variables.choiceValue) eq
0)>
<!--- ignore it --->
<cfelse>
...
</cfif>
A simple bit of boolean algebra:
not (A or B) == (not A) and (not B)
