I am using a drop down box in a form, the method is GET. The data  
that  
i am selecting in the box is not getting stored in the database. But  
when i am not using the drop down box the rest of the data is getting  
stored. I stored the submitted form data in an instance variable.  
When  
i am trying to print the instance variable no output is coming…  
Can anybody tell how to get the selected data in the drop down box in  
the other form?

People can’t help you if you don’t show them what you are doing.

Are you doing it like this  
\<%= collection\_select(:product, :Product\_ID,  
Product.find(:all), :id, :Product\_Name) %\>
