Technical Details

The entityID is assigned fairly frequently when this template is used by groupID is rarely assigned - so this addresses when including the file - and could probably be done in other places that include it

Looks good, resolves the warnings. I imagine there is a reason for groupID='' instead of NULL?

[eileenmcnaughton]

@larssandergreen no not really - I thought about NULL & then thought 'maybe that is wrong' - but I'm not sure it was

[larssandergreen]

@eileenmcnaughton You were right, NULL is wrong. Not sure on the details, but when I tried it, the warning was gone, but I got another warning for a variable that was within the if. Using '' instead works as expected.
