Vb if condition question

[xxfullclipxx]

Okay say i create 3 custum fields. now i want to have them set up in my postbit. But i dont want it to appear unless one of these fields is filled.


Now I want to have some text above

<vb:if condition="$post['field5']"> <center>Text Here</center>< /br> <vb:if condition="$post['field5']"> | vb:if condition="$post['field6']"> | <vb:if condition="$post['field7']">

Now how do i begin that instead of field5 what would i add that if any of them fields were filled out that it would load. at the moment that would only show if field 5 is filled. even if field6 and 7 were filled. i need it to show if field 6 is filled or 7. or just one of them, i think you would understand what i am saying. i have these fields in a category so if i have to call the category i can.
