Need help with php

[plot]

Okay, how do i put this option in 'Edit Options' rather than in 'Edit Profile'. Also, how do i make the selection a dropdown menu rather than a list of options.

I do not want whether my user has enabled or disabled this option to appear in their post bit but just disable a code.

Also, do i replace 'FieldX' with the name of of my new field?

<if condition="$bbuserinfo['googads']">no ads<else />ads</if>

or do i do this?

<if condition="$bbuserinfo['enable']">ads<else />no ads</if>
