I need to use specific colours in my calendars that are not on the standard drop down. Using some (all?) of the standard list everything works fine.
I tried putting a 1 in the active column next to some unactivated colours in the colours layout and it duly added them to the drop down, but these colours cause an error when I test the setup:
Error 507: Value in field failed calculation test of validation entry option
Using a hex value also causes the same error.
What am I doing wrong please?
Thank you!
