Need Help : Multiple field settings for user list in refrences based view

Hello,

I have content type in which i have one field named as Users. Here, at time of adding data, admin can select "n" number of users from particular role of users of website. I have used user references for this in content type.

So this means like following.

Node 1 : User1 and User2 : NID : 1
Node 2 : User2 and User2 : NID : 2
Node 3 : User1 and User3 : NID : 3

Now i have one another CCK say Transaction. Here i am using node references from URL. So it will generate URL something like http://site.com/node/add/transcation/1?destination=node/1 to enter data for Node1 related transaction.

Now this Transaction CCK has one field termed as related user with dropdown. What i want is that, if i select node 1 entry then i should get related users only which are User1 and User2. User3 should not be in list.

Somehow i made one view with references and assigned it to that dropdown by using node references type but it display data in dropdown like
user1, user2 instead of
user1
user2
screenshot attached.

I have already tried check and uncheck for "Show Multiple field settings" in views.

Can anyone let me know how to solve this ?

Thank you
