     in TFS , I need to select multiple values on custom field/drop down , used multi value control.  It's working fine. But I need to do one step ahead , Want to use it conditionally. 
In two custom fields , here I want to apply WHEN Condition to display different values on selecting particular Value in particular custom field These value should be multi valued control. Kindly share if there is any way to use Multi values on WHEN condition.

Here is the message appeared when I do ::

Field Name... doesn't have any value to list in the multi value control....

Thank you.
