Hi all,

I can't get my head around this error in my query:

I would have expected the negative index to refer to a missing value but I have re-entered all column names in case of any cheeky spaces or capitalisation differences, to no avail. Am I missing something obvious? The funny thing is that nothing should have changed since the last time this query was run and I can't really understand why this would suddenly pop up.

Any advice would be greatly appreciated!
