Hi,

With this area I could calculate the results last week, all my Excel spreadsheets exist and have the content enabled, moreover, those ranges are defined and with correct values.

Do you have any suggestions to help me overcome the error and be able to calculate the results?

Regards

Estela.

this usually happens when you are actively editing the excel file, or excel has a message pop-up open that you haven't click "Ok" or "Cancel" on. Try closing out excel and rerun your model to see whether the error persists.

best,

Charlotte
