trying to feed my multiple spreadsheet with data but stops fetching

[Jendelheim]

I got this external .xlsx-file where a script adds certain rows with information that I want fetched in to multiple spreadsheet. I've managed to do this while not operative, I can see that my tab that represents the data do change when I add data in the external document. But now I can't add a BetAngel market to the spreadsheet, if I go in to "Excel Sheet" in Guardian nothing appends in the spreadsheet. I have to open the spreadsheet via BetAngel which opens a new Excel window with the spreadsheet, the market is fetched and I can see all live market action - but the connection with my external document is now gone. What can I do? Is there any other easier way to continuously check an external .xlsx file to add that information in to the multiple spreadsheet?

Best,

Victor
