hi,  
im gettin lost with the subject. need some pointers:

Usermodel:  
validates\_presence\_of :companyname, :if =\> :is\_company?

\<%= f.label "Are u representing a company?" %\> \<%= f.check\_box :is\_company, :onclick =\> "new Effect.toggle('div\_company'); //if($('user\_is\_company').value == 0){$('user\_is\_company').value =1;} //if($('user\_is\_company').value == 1){$('user\_is\_company').value =0;} //alert(escape($('user\_is\_company').value))" %\>

 Details 

\<%= f.label "Company Name" %\>  
\<%= f.text\_field :companytitle %\>

......

my problem is:  
if someone is signing up AND checking the box “is\_company” the company  
detail div appears. now, if the company details dont pass the  
validation,  
the page gets naturally reloaded and the checkbox is\_company stays  
checked  
but the div is hidden.

tried several ways , but all end up in chaos…

does anyone have any working snippets?/thx

You need to add condition, where if a box is checked show div.
