This is great. I implemented it on my site this morning. I added it to the
bottom of the Since Midnight table at the bottom. Does exactly what I was
looking for.
The only issue I'm having is that I want to display the rain total only if
it's not zero. I live in an area where there's typically no rain from May
to October so I want to skip the line for the rain when it's 0. I tried an
if statement but it's not effective. Any hints?
Here's the template code:
<tr>
<td class="stats_label">
On This Day<br/>
$day.dateTime.format("%b %d")
</td>
<td class="stats_data">
#for $day in $this_span.periods
$day.dateTime.format("%Y")<br/>
H: $day.outTemp.max  L:
$day.outTemp.min<br/>
#if $day.rain.sum > 0
  Rain: $day.rain.sum<br/>
#end if
#end for
</td>
</tr>
