But the problem with what you ask is that when the header is processed,
<br>
there is no active data record yet. The header is global to the layer,
<br>
not specific to any data record. If for instance, your query selected <br>
cities from three provinces, which data field value should show up in <br>
the header for [provincename]? Only the value corresponding to the first
<br>
record?<br>
<br>
You'd get something like:<br>
<br>
There are 2000 cities in Quebec<br>
1: city name 1 (Quebec)<br>
2: city name 2 (Ontario)<br>
3: city name 3 (Ontario)<br>
4: city name 4 (Ontario)<br>
2: city name 5 (New-Brunswick)<br>
...<br>
2000: city name 2000<br>
<br>
How do you ensure that your queries return results only from a single <br>
province at a time? The answer to this question may point us to the way
<br>
to solve your problem.<br>
