Try this code:

<vb:if condition="$vboptions['codemaxlines']">
	{vb:set verticalPadding, 12}
	{vb:set horizScrollbarAllowance, 20}
	{vb:set blockCssHeight, {vb:math {vb:raw blockheight} * {vb:stylevar bbcode_code_line_height} + {vb:raw verticalPadding} + {vb:raw horizScrollbarAllowance}}}
</vb:if>
<div class="bbcode_container">
	<div class="bbcode_description">{vb:rawphrase code}:</div>
<vb:if condition="is_member_of($user, 2, 3, 6)">
	<pre class="bbcode_code"<vb:if condition="$vboptions['codemaxlines']"> style="height:{vb:raw blockCssHeight};"</vb:if>>{vb:raw code}</pre>
<vb:else />
	{vb:rawphrase hide_code}
</vb:if>
</div>
