Question : How do I get a static value list to show when I have a parameter prompt another parameter?

I am building a report that has a parameter that fills 2 date parameters.  Call this parameter A.  The parameter is a function that returns 2 dates, a start date and end date,  and each date is placed into separate parameters by using dynamic values.  The two date parameters are then used to build a SQL command to build the report.  Parameter A is a string and it returns 2 dates.  So if I enter "QTD" into the parameter it would return the start and end date of the Quarter to Date.  I have entered static values for parameter A and when I refresh the report, the value list doesn't appear.  I have to enter the string manually.  The report works fine when I type in the specific value but I need to have a list for the user to choose from.  Why doesn't the value list appear in the prompt?  Is there a way or trick to get the list to appear?

If parameter A isn't used in the report you won't get prompted for it.
