Please help: making alternating row background color in threadbit?

[way2xtreme]

Hi

I am trying to set alternating row background color in threadbit. After searing around, I found this:

I altered the code (see below) and tried it to find I am getting only "alt1" from {vb:raw $altclass} .

Maybe there's something else I need to do?

Please help and thank you in advance

<vb:if condition="!isset($altrow)">
<vb:if condition="$altrow = 0"></vb:if>
</vb:if>
<vb:if condition="++$altrow % 2 == 0">
<vb:if condition="$altclass = 'alt2'"></vb:if>
<vb:else />
<vb:if condition="$altclass = 'alt1'"></vb:if>
</vb:if>

...{vb:raw $altclass}
