Hi RobTrew, thank you for making the script. I am trying to use this script to set the start date for a task where I have entered in the due date, and I want the start date to be 1 week before the due date. I typed in dd=sd-1w but I get this error:

Error Number:Canít make missing value into type number.

I've also tried dd=sd-7d but that doesn't work either. Do you have any idea why? Any help is appreciated!
