Limiting 'Allow Multiple Parameters' 1

[hpl2001]

Hello:

Programming with Crystal 8. I have a report with a parameter that I would like to accept a maximum of 10 values. Is there some way to limit the entry of multple value parameters to 10? If not, how can I capture the extra values in the report and display them? The report itself will only process the first 10 values, but I want to let a user know if some of their requests are not filled.

TIA

Holly

Use UBound({?your_multiValue_Parameter}) funtion to find out how many items were specified in the parameter.

You can then detect having more than 10 items, return False in the record selection to block the report from running, or unsuppress a formula showing a warning and the list of items beyond the 10th position.
