I am using currently using LEAP 2020.1.85 and when running results, I get an error from an expression that uses a linked excel file (see image). When I click ok, save, and run results again (with no changes to the model, it will calculate again and read the excel file fine but then a new error message will appear (same error, different excel file). I can repeat this process until the model is done calculating. How do I stop this error from happening so the model runs all the way through? Is it an issue with the Excel program or an issue with LEAP or my model? In a previous version of LEAP, this model had no issues running.

Thank you,

Matt
