Custom profile field conditionals for check boxes

[WorldCraft]

Hello. I'm trying to get some conditionals working for a Multiple Selection Checkbox profile field I've set.

I tried the following conditional, but it doesn't work with checbox values:

<vb:if condition="$bbuserinfo[fieldX] == 'Show Me'">
<script> Do stuff here </script>
</vb:if>

However, it works fine with Radio button values. I am making sure that the fieldX and Field ID's match, and that the option names are matching exactly as well.

Any ideas why it doesn't work with checkboxes?
