Hello All,

I am very new to Web D. (in general) and Ruby on Rails and  
have been stumped on this for awhile.

In my view I have a check box of which I need to grab a primary key  
value when checked.

The primary key value will then need to be used to generate and  
populate a corresponding drop down list.

Currently the data generated to view is similar to …

Telephone (primary key of 1) [check box] … web user clicks check box  
then I need to display corresponding database data based on the  
primary key

Internet (primary key of 2) [check box] … same concept for  
Telephone using Internet PK

Television (primary key of 3) [check box] … same concept for  
Telephone using Television PK

Can anyone please help me?

Rachel

If you need to have a checkbox you can allways just use an image of a  
checkbox. or a button\_to…

goes. Thank you so much for the reply… heimdull
