Trouble setting data source

[FRED_EMMERICH_(Guest)]

I am using the runtime .dll with 8.1 SQL. I call getRuntimeRecord() in order to be able to prompt a user for a value in the report. I used to use chooseReport(). Next I call chooseDataSource() to select the data source. Problem is, even though this call is error free, R&R still uses the data source saved with the report. What am I doing wrong?____Thanks,

I have all my issues with prompting for user input straightened out. I am back to calling chooseReport() and all works fine except when I do chooseDataSource(), I get no errors, but it also does not change the data source. The book says I do not need to call setDataSource(). I will try that and see what happens.
