if 3 selected then

loop 1 3

do something

end loop

i want process in same page. can let me know need do? tried cfselect , radio buttons no luck. thank you.

i think you're on thinking problem. form return value of selected radio button.

html:

<form method="post" action="">     <p>how many want?!? choose now!</p>     <input type="radio" name="varname" value="1" onclick="this.form.submit();">1     <input type="radio" name="varname" value="2" onclick="this.form.submit();">2     <input type="radio" name="varname" value="3" onclick="this.form.submit();">3     <input type="submit"> </form> 

coldfusion:

<cfif isdefined("form.varname") , form.varname gt 0>     <cfloop index="i" from="1" to="#form.varname#" step="1">       <!--- stuff --->     </cfloop> </cfif>
