Hide warning if % is 0

[Gstone]

Hello again,

i'm have about 0 knowledge when it comes to php/if statements, but I thought this might be an easy one for those that know a lot:

if a member has 0% warning level (as shown in postbit), how would i go about hiding it? something like "if user warn level = 0, then hide" otherwise, it would show up.

this is what is in the postbit, and I figure I have to wrap the if statement around it:

{$post['warninglevel']}
