Using Calculated Columns in Formula within another Calculated Column in SEI

SOLVED

[SEI v.8]

Can I reference a Calculated Column I created in the calculation of another Calculated Column?  If so, what is the syntax to refer to a Calculated Column within the SQL Scripts Builder?  Usually when referring to to a field within a calculation the syntax is 'table.fieldname_0' (ie ITMASTER.ITMREF_0).
