display content based on custom profile fields?

[wtrk]

I need some help. Id like to display some different content depending on the answer to the custom profile field question, but Im having some issues and have a few questions.

1) Is this the correct code to display the content based on the profile field (check boxes):

<if condition="$post[fieldX] == 'Answer'">
content shown here
</if>

2) Is the answer the name of the check box? And if the check box name is two or more words, do I just put that in quotes like this:

<if condition="$post[fieldX] == 'Answer Two'">
content shown here
</if>

3) Is $user[filedX] better to use than $post[fieldX]?

Thanks.
