Modify excel file for data scrapping

Hello, I need to modify (or make a new one) an existing file excel that used to download data from Yahoo Finance and calculate some formulas. The file now is not working anymore, can you please fix it? In addition, I would like the file to download multiple stocks data simultaneously and then put the results of all the selected stocks in one tab only. Please see the file to understand. The data can be from Yahoo Finance or (even better) from Excel Stocks Data. Thanks
