Try to control again the configuration of your custom user field. Maybe it contain the error.

However, if you've set your custom profile field with Options, you could use this type of code:

<if condition="$post['fieldX'] & 1">
    CODE TO DISPLAY IF OPTION 1 IS SELECTED
</if>
<if condition="$post['fieldX'] & 2">
    CODE TO DISPLAY IF OPTION 2 IS SELECTED
</if>
<if condition="$post['fieldX'] & 4">
    CODE TO DISPLAY IF OPTION 3 IS SELECTED
</if>
<if condition="$post['fieldX'] & 8">
    CODE TO DISPLAY IF OPTION 4 IS SELECTED
</if>
<if condition="$post['fieldX'] & 16">
    CODE TO DISPLAY IF OPTION 5 IS SELECTED
</if>
<if condition="$post['fieldX'] & 32">
    CODE TO DISPLAY IF OPTION 6 IS SELECTED
</if>
<if condition="$post['fieldX'] & 64">
    CODE TO DISPLAY IF OPTION 7 IS SELECTED
</if>
<if condition="$post['fieldX'] & 128">
    CODE TO DISPLAY IF OPTION 8 IS SELECTED
</if>
