Hi,
I have an optional parameter in CR2008; I would like to print the choosen parameter values into the report header. This works great by using this function:
Join({?MyParameter},", ")
However, when no values were selected I get the error message "Parameter has no value".
So I adapted the function:
if hasvalue({?MyParameter}) then Join({?MyParameter},", ") else "All records"
The function is correct but I still get the error message (error dialog window).
How can I suppress the error message?
Thanks!
