  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This custom function takes a date range and a text constant (ID) and constructs a multi-key that has the ID on every line. It builds the multi-key to contain each of the dates in the date range from StartDate to EndDate.

This function could be easily modified to allow a text constant to be appended to each line of a return-separated list of values.

Brilliant--thank you. I adapted this for numbers instead of dates and it works marvelously.
