Thanks Gergely.
I haven’t looked at marquee editing or any other methods, so this just refers to moving hotspots.
I wonder if the error may be that I’ve converted the values to strings, and these don’t directly update, as they’re only translated when the settings dialogue is opened.
However, when I tried some mathematical calculations on the ROOM_AREA parameter (eg calculating acres via area_acre2 = (ROOM_AREA*0.00024710538146), it throws up an error saying
Operator can be used only for numeric type operands
(area_acre2 is an undefined parameter type in the example above)
Any help on how I can get round this?
Thanks,
Derek
