Radio Button Error

I’m using the following code to show the data of a radio button:

{if radio}
{premier_member}
{if option_value == "Yes"}{option_value}{/if}
{/premier_member}             
 {/if}

The output is correct but I’m getting these notices when I’m using this code:

A PHP Error was encountered Severity: Notice Message: Undefined index: channel_html_formatting Filename: radio/ft.radio.php

Line Number: 147 A PHP Error was encountered Severity: Notice Message: Undefined index: channel_auto_link_urls Filename: radio/ft.radio.php

Line Number: 148 A PHP Error was encountered Severity: Notice Message: Undefined index: channel_allow_img_urls Filename: radio/ft.radio.php

Line Number: 149

Any ideas why?
