Set Variable querying two lookup fields

Hi there,

I have implemented setting a variable from a lookup list using the Nintex Workflow Designer 2010 with no problem.

The global variable is set when the value of a field in my current workflow item (ListItem) matches a value in my lookup list and then brings back an email address so the task is dynamically assigned to the relevant person.

I need to extend this functionality to query on two fields form the lookup list rather than one. (the second one being hard coded)

Is this possible, if so can you tell me how?

Many Thanks for any help you can provide

Simon
