hello, I am trying to display a Textarea if a user checks the checkbox  
and hides the textarea if the checkbox is not clicked. I can get the  
display working properly, however the actual checkbox is not actually  
checking. It is staying blank (not checked) no matter how many times I  
click it.  
Here is my code

\<%= check\_box “event”, “has\_policy”, “onclick” =\>  
“Effect.toggle(‘policy’); return false;” %\>  
Yes I want add a policy/terms  
agreement

 \<%= form.text\_area :policy\_a, :id=\> 'field19', :cols =\> 50, :rows =\> 10, :class =\> "medium" %\>

I’m guessing that “return false” is preventing the onclick from taking  
its default action, which is to check or uncheck the box.

So if you try ‘return true;’ is it always checked?

I thought same thing. I tried that as well, but it broke the Toggle  
event.
