How do I concatenate two fields in order to label?

If your data is spread across two attribute fields, and you want to join them together in order to create a single label, you will need to create a new field that joins them together.  In order to do this, open the Edit Attribute Schema dialog and add a new field.  Once the new field is added, with the name, type, and length set accordingly , you will need to add an expression that adds the two fields together.  

The formula for adding two string fields together is as follows:

(column1)& " " &(column2)

In this formula, the '&' operator is specifically used for concatenating strings.  Also,m be sure to include the " " as it will include a space between the two strings being joined.
