    You could include some more diagnostics in your output, for example,
    before the 'each' loop try displaying @employee.size to see if there
    is anything there. The symptom suggests that it is empty.

    Also have a look at the Rails Guide on debugging, in particular how to
    use ruby-debug to break into your code to inspect data and follow
    flow. If you find that @employee.size is 0 then break into the
    controller code that sets it up to see what is going on.

    What does the value of your @employee variable look like. Where do you
    assign it?

    hi,

    I assigned it my controller like
    @employee = Employee.find(:all,:conditions => ["exp =?",params[:exp]])

    i tried it by putting each loop in controller and it workes well, but
    in case of popup box its not working
    and also @employee.size is also not displayed in popup

    thanks,

    Did you try removing the :conditions so it is just .find(:all) to see
    what happens?
    By the way, you should really call it @employees so you know it is a
    collection not just one employee.
    i tried it by putting each loop in controller and it workes well, but
    in case of popup box its not working
    and also @employee.size is also not displayed in popup
    What do you mean it is not displayed, if you do
    size: <%= @employee.size %>
    what do you see?

    What did you learn by using ruby-debug and breaking into the controller code?

    Is that supposed to be an answer to one of the questions previously
    asked? You have given no indication of which one, nor have you
    answered some other questions.

    Please reply again to whichever post you are replying and insert your
    message inline at appropriate points in the previous post so that we
    can see what you are replying to.
