Help converting a short template mod to VB4

[Booost This]

I had this installed on my 3.x forum and worked flawlessly, however with the vb4 upgrade I just did I am completely out of date with the new code structure of vb4. Can someone lend a hand as to what I need to do to get this to work now? It was a great add-on for our board.

It was lifted and customized a little more from this original mod.

This is how I last had it running on VB 3.5+ up until I installed to vb4.

This is in the postbit template.

<if condition="$jointime > 3285"><img src="$stylevar[imgdir_misc]/star.png" /></if>

<if condition="$jointime > 2190"><img src="$stylevar[imgdir_misc]/star.png" /></if>
<else />
<if condition="$jointime > 1460"><img src="$stylevar[imgdir_misc]/star.png" /></if>
<if condition="$jointime > 1095"><img src="$stylevar[imgdir_misc]/star.png" /></if>
<if condition="$jointime > 730"><img src="$stylevar[imgdir_misc]/star.png" /></if>
<if condition="$jointime > 365"><img src="$stylevar[imgdir_misc]/star.png" /></if>
</if>
</if>

Any help would be greatly appreciated!
