Hi I have a master document with lots of formula's that links to another document that holds raw data for 2018. I want to make copy of the master document and link it to a different document i.e the raw data for 2019. Essentially I just want the master document to look at a different file for the values however if i try "change source" and select the 2019 document if comes up with reference error.
Many thanks in advance
