The problem is that the "primary" value is being stored in the current
tiddler, but when you are referencing it in the filter, it is relative to
each matched [tag[Company]] tiddler.
Also, the filter syntax, "<primary>" is references a variable, not a
field. Thus, to actually refer to the selected value stored in the
*current* tiddler, try this:
<$select field='primary'>
<option value='^185'>1850s</option>
<option value='^186'>1860s</option>
<option value='^187'>1870s</option>
<option value='^188'>1880s</option>
</$select>
''year:'' {{!!primary}}<br>
<$vars primary={{!!primary}}>
<$count filter="[tag[Company]regexp:charterfiled<primary>]"/>
</$vars>
Let me know how it goes...
enjoy,
