Neighbor is down alert swql string shows in alert

In the included alert "Neighbor is down" I added the following swql to show the node caption so we know what the name of the neighbor is. When the IP address does not match a known node then I get the wsql string in the alert email.

Is there a way that If it can't find a node then make it blank?

${N=SWQL;M=SELECT NIP.Node.Caption FROM Orion.NodeIPAddresses NIP WHERE (IPAddress = '${N=SwisEntity;M=NeighborIP}')}
