I compared your template to a default template and you have the correct css in there - it wasn't taken out.
HTML Code:
<tr valign="top">
<td class="alt2" width="200" style="border: $stylevar[cellspacing]px solid $stylevar[tborder_bgcolor]; border-top: 0px; border-bottom: 0px">
Looking at that, it should end up something like this (this is an example):
HTML Code:
<tr valign="top">
<td class="alt2" width="200" style="border: 1px solid #D1D1E1; border-top: 0px; border-bottom: 0px">
Check your page source and see if it is turning out like that or if the border is being set to 0px. If so, you need to either change $stylevar[cellspacing] to 1 (under StyleVars) or change the template and replace $stylevar[cellspacing] with 1.
