Hi Ravi,

The strategy is to configure your multivalue input with using prefix, sufix and delimiter, like this:

<fieldset submitButton="false">
<input type="multiselect" token="field1">
<label>field1</label>
<choice value="value1">value1</choice>
<choice value="value2">value2</choice>
<choice value="value3">value3</choice>
<delimiter>,</delimiter>
<prefix>| stats sum(</prefix>
<suffix>)</suffix>
</input>
</fieldset>

Via UI it will look like this:

So in your search you'll simply do:

|makeresults $field1$

where |makeresults is your actual search. The token will append | sum(<selected_values>)

Then you can add the proper grouping fields and etc to make that happen as you want it to. (like add the "as Total by Jobname" after the ")" suffix
