Help - Main report does not pass data to subreport

Hello and thanks to all who reply.

Overall report pulls medical history about patients. The data pull centers around the patients medical insurance card ID number and sub-members of the said ID number.

Here is my design; the main report is a SQL Command designed to ask the user for the main medical ID number. The first prompt is one to ask the user for the ID number (static string parameter). It then goes out and gets a list of sub-members based on that ID Number. A new set of prompts appear that are linked to the sub-report SQL command the first ask the user add any or all of the sub-members (dynamic parameter) to the list. Below that prompt, a nother set ask the user to type in a beginning and ending date range for the data pull (because how the date range is formatted I have to do a string static prompt).

 

Now the Sub-Member dynamic list is used as a crystal reports filter and not passed into the sub reports SQL Command. The Beginng and Ending date, and the Main ID Number are passed to the sub-reports SQL Command.

 

Here is where the report breaks down. The original member ID that was inputted from the main report gets flushed before it can be passed to the sub-report. I am base this on what I observe from when I run the report. After I input the ID Number and the 2nd set of prompts appear asking for the sub-members and date range the ID Number parameter is still at the top but blank. Later, after the report is ran I look at the 'Show current parameters value..' from the Report menu and it shows as empty. If I rerun the report and do not leave the 2nd Main ID Number prompt but type in the number again the report works fine. If I change the Sub-report ID Number link to a dynamic prompt, on the 2nd set of prompts the top one is dynamic and the ID Number I inputted is the first and only thing in the list. If it is chosen then the report works as I would like.

However, this report is for the general  co-worker population and I would like to not have them have to type in the main ID Number in twice or even have them chose it again from a dynamic list.

 

I have tried shared variables and built the report another way and the same thing happens. When the dynamic list of sub-members is shown the data from the main report is flushed except for the list of sub-members.
 

 
Is there a way to fix it so the ID Number gets passed correctly or have the dynamic prompt default to the first item in its list. Or is there some other way to fix this?

 

Thank you for your help.
