I am trying to have the user select a drop down, which will then update a page param, and then have a link on the page use that param. My problem is that when the user chooses the drop down, the param for the page is not being updated and the link is not passing the category_type param.
Error from the development.log
NoMethodError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.value=):

<select id="category_type" name="category_type"> <option value="Type1">Type 1</option> <option value="Type2">Type 2</option> <option value="Type3">Type 3</option> </select>
