Hello,
I have date parameter in a report, this works fine and allows me to
manually enter a value such as 2007-06-19.
However I would like for this parameter to have a default value which is
dynamic - such as the current date or the current date minus 1 month etc.
How can this be achieved ????
I have set this parameter in the 'initialize' method of the report (
using params["paramDateEnd"].value = ..... ) however this seems to run
after the parameter UI is displayed.
Thank you kindly,
Damian

Thanks Jason,
I'll have a crack at what you've suggested hopefully next week.
Kind regards,
