Dynamic Command Parameter Prompts twice for Value

Question

I am having trouble in CR 2008 with command parameters.  Whenever I make the command parameter dynamic, I am prompted twice for the value: first I'm prompted to enter the value freehand, then the second prompt is a dropdown list with just the freehand value (or an error if the freehand value does not exist in the db).
I need to use dynamic command parameters for two reasons: 1) to allow users to select the value from a dropdown list rather than a free-text value, and 2) to limit the record set returned from my initial command query.
Any help on how to get dynamic command parameters to display all values in a dropdown list, and in one prompt, is appreciated!

Hi
If you create a parameter in your command it will be always static.  You can't make this as dynamic because, once your command get executed only you will get values in your report or in your list of values (dynamic parameter).
There is a work around for this :
--Create a report with command without any parameters at command level
--Create a dynamic parameter at report level and do not place any fields in your report.
--Now insert your orginal report as sub report in Report footer.
--Right click on your sub report and go in change sub report links and link Main report dynamic parameter to your sub report command parameter.
--Suppress all other section in your main report.
Now when you refresh, it will execute your main report dynamic parameter with pick list.  Once user selects a value it will be passed to your command parameter.
