Division by zero problem.

I am not a coder so I am hoping someone here can help me with a p[roblem I am having witha module for vbadvanced cmps. I added a "latest links" module and I get was trying to get a rating image to show and I get this error:
Division by zero in /modules/latestlinks.php on line 69

Line 69:

Code:

$link['truerating'] = vb_number_format($link['votetotal'] / $link['votenum'], 2);

Im sure this is an easy fix but I am not a coder. Can anyone help a brother out?

I should mention that this only happens if there is a link with no votes. If a link has a rating the error doesnt show up.

Simple... if it has no votes, then you are dividing by zero when calculating your average. Try this,

PHP Code:


		
			
$link['truerating'] = $link['votenum'] ? vb_number_format($link['votetotal'] / $link['votenum'], 2) : 0;
