Apologies - I didn't explain very well.
I have tried using ctrl+F9 in the insert field box. This does not work.
So I have done it straight into the document. I have tried every combination of Making the outside {}first, then doing ctrl+f9 for the inside {} as well. Deleting the spaces, etc.
I get the error (Upon right click and 'update field')
Error! Unkown op code for conditional.
I have never worked with fields before I'm afraid, but I am using ctrl+f9 for the {} as specified.
I am so happy to know this can be done, but am just struggling to get there
