[support] Taxonomy in views reference

[Roger]

I have Name, Last Name, Phone number fields in a taxonomy Vocabulary 
named Contacts.

I have a Views Reference named Contacts which displays Name and Lastname 
fields.
All works as expected.

When I set up a Contacts  field in my events table form set to Node 
Reference I want to select the Reference View but get error message from 
'Views- Nodes That Can Be Referenced' = No eligible view was found.

The idea is to provide a drop down list in Events form that provides 
first and last name from the taxonomy view.

I'm completely stuck on how to do this

Are there any Views experts who can help me please?
thanks
Roger
