I noticed that the parameters must be entered in as a range. It would be nice if you could include numerical values in there so that the following would work:
This has been done on purpose at this stage.
Range variables are initialized as "empty"
"Double" variables are initialized with a default value of "Zero".... and 0 can be a value you want to display.
I will have a look at it anyway.
Thanks for your feedback.
this suggestion has been implemented in v3.0
