it got sumbmitted before writing Q:),  
ok so iam using  
\<%= check\_box\_tag ( “id”,“word”,false, :onclick =\> remote\_function( ))%\>  
for sending remotecall but i want “id” and value ie “word” to be diff  
as i load

like iam looping through records as shown below

\<%for x in @xrecords%\>  
\<%= check\_box\_tag ( “\<%x.id%\>”,“word”,false, :onclick =\>  
remote\_function( ))%\>  
\<%end%\>  
but this is not taking \<%x.id%\> but throwing exception,please let me  
know if there is a way to do this ie assigning the id dinamically as i  
loop

Hi Vasu,

You need to be putting x.id within curly brackets so that it reads:

\<%= check\_box\_tag ( “#{x.id}”,“word”,false, :onclick =\>

> remote\_function( ))%\>

That should stop the exception.

Kind Regards
