When I use the <$count> widget, (no more fruit - this is the actual content 
I'm dealing with)

<$list filter="[all[current]fields[]]" variable="fieldname">
<$list filter="[all[current]get<fieldname>prefix[1]suffix[1]]" 
variable="dummy" >
<$list filter="[title<fieldname>getindex[origin]]" variable="origin">
 <<origin>>:<$count filter=" <<origin>>"/><br>
</$list>
</$list>
</$list>

I get a list like this:

cbm cbm.midline:1
pmrf:1
pmrf:1
[[opp motor cortex]]:1
pmrf cn8:1

There are 2 obvious problems: 
1) the count treats each "sentence" (a line from a data tiddler) rather 
than each "word", and
2) the count is only valid for each "pass" through the filter, so 
everything will come out as "1"

So I thought the best start would be to assign the output of the whole 
filter to a field for further processing.
The filter set to output just "<<origin>>" by itself results in "cbm 
cbm.midline pmrf pmrf [[opp motor cortex]] pmrf cn8", 
which should be easier to deal with, but this doesn't seem to set the 
results in the field "aaa" of the current tiddler:

<$list filter="[all[current]fields[]]" variable="fieldname">
<$list filter="[all[current]get<fieldname>prefix[1]suffix[1]]" 
variable="dummy" >
<$list filter="[title<fieldname>getindex[origin]]" variable="origin">
<$action-setfield $field="aaa" $value="<origin>"/>
<<origin>>
</$list>
</$list>
</$list>

I tried all of the following

$value="<origin>"
$value=<origin>
$value="<<origin>>"
$value=<<origin>>
$value="$<origin>$"
$value=$<origin>$

but none of them resulted in a field "aaa" at all, let alone one filled 
with the proper content.

Just before posting this I tried all variations of:

<$action-setfield field="aaa" value="<origin>"/>

i.e. I spotted that "field" and "value" didn't need the "$" like the 
"$tidder" would in the tiddlywiki.com examples


What am I doing wrong here?  I should be able to get that filter-produced 
string "cbm cbm.midline pmrf pmrf [[opp motor cortex]] pmrf cn8" into a 
field, shouldn't I?
