Facing Problem in Configuring Radio buttons

Hi,

I have a requirement as follows:

There are two  fields:

A1 - Input field

R1 - Radio button field

Now I need to display the fields as mentioned below,  in ONE ROW of left Panel

.

I to J                   K to M                          N to P

A1.label            A1.field value             R1 (2 radio buttons with no label)

When I am trying to do this, I am getting an error for Radio button field, saying:

Element must cover the entire panel

Error in property value

Could you please help me out to solve my issue..

Thanks for the needful..
