How to transfer the information in the database into input:Radio - Codes Helper

below is the form I use to update the broker data. There is a value of radio that I need to enter in the form. I take the value of the database and fill it into the input item. But only radio, the property of type, is not checked. So I wrote a paragraph in script, that when the update table pops up, the performance of this radio is check. But it didn"t work. Ask what should be done to reflect the type attribute passed in.

addBrokerForm.jsp
