I am trying to do a simple bit of logic to add an empty table row if two
conditions are met but the Cheetah generator is throwing up a syntax error
and I can't work out why. This loop generates a table of high tides, but if
the first tidal event is low tide I don't want the high tide displayed in
the row as it will be after the low tide. The code is:
<table class="table table-striped text-left">
<tr>
<td><b>Date</b></td></td><td><b>Time
(local)</b></td><td><b>Height</b></td>
</tr>
#set $tides = $forecast.xtides
#set $counter = 0
#for $tide in $tides
#set $counter = $counter + 1
#if $counter = 1 and $tide.hilo == 'L' <-- error generated here
<tr>
<td>-</td>
<td>-</td>
<td>-</td>
</tr>
#else if $counter < 28
#set $height=$tide.offset.raw / 3.281
#if $tide.hilo == 'H'
<tr>
<td>$tide.event_ts.format("%a %d %b")</td>
<td>$tide.event_ts.format("%H:%M")</td>
<td>
#echo '%.2f' % $height
m </td>
</tr>
#end if
#end if
#end for
</table>
And here's the error:

The code works fine without the empty row logic, and both the $counter and
$tide.hilo variables are working in the rest of the code, just not when I
try to use them in a logic statement.
