Here I suggest to keep Dashboard A's Value and Threashold logic in Dashboard B.
Like...
Copy search from Dashboard A and use it to set token in Dashboard B.
See below sample XML for same. Here I have used search from Dashboard A (for example) and add condition in search as per your requirement (like. I added in below XML | where Value=90 AND threshold=80). You can see a token tkn_data which is set on the basis of search results. You can use this tkn_data token in your dashboard. You can validate the XML by modifying Value AND threshold value in search.
<form>
<label>Dashboard Example</label>
<search>
<query>| makeresults | eval Value=900,threshold=80 | rename COMMENT as "This is sample of your search" | fields Value threshold| where Value=90 AND threshold=80 </query>
<earliest>-24h@h</earliest>
<latest>now</latest>
<done>
<condition match="'job.resultCount' == 0">
<set token="tkn_data">Other Value</set>
</condition>
<condition>
<set token="tkn_data">My Expected Value</set>
</condition>
</done>
</search>
<row>
<panel>
<html>
<b> Results from search manager: $tkn_data$</b>
</html>
</panel>
</row>
</form>
I hope this will help you.
Thanks
