Make additional comments mandatory on survey

[abc_001]

The Survey is configured and there are some questions on it. It has a numeric scale with each questions.(radio button) If user selects ( 1 or 2 ) very poor, the comments box will become mandatory. For other values (3,4,5,6) it will be optional to fill.

Can anyone help me with this ?

Please help me on which table we can write the client script.
