Radio button validation

[ahksar]

Hi,
When I try to submit a form with radio buttons, and none of them are selected, I get an error when I try to insert it into the DB. I want to allow my users the option of not selecting a radio button, and to insert a default value if so.
Can i use something like this in the INSERT page?
<cfif NOT IsDefined(&quot;#form.strStrike#&quot>
<cfset &quot;#form.strStrike#&quot;=-9>
</cfif>
strStrike is the name of the radio button.
and the rest of the SQL insert statements follow here...
Thanks

<cfif Not IsDefined(&quot;form.strStrike&quot>
<cfset somevar = -9>
<cfelse>
<cfset somevar = #form.strStrike#>
</cfif>


OR...................


<cfparam name=&quot;form.strStrike&quot; default = &quot;-9&quot;>
