Paul - Thanks so much! I'm taking your "IF..." statement to mean, "If the field contains "Yes," substitute "electronic" and otherwise substitute "hardcopy". I'll try to acquire a better understanding of how "IF..." works. Thanks again for putting me on the right track.

See the Field Codes Reference for IF Field
{ IF Expression1 Operator Expression2 TrueText FalseText }


Sometimes quotation marks around things are needed since the field uses spaces as delimiters.
