excel formulas are not working

Hi Sergei, I'm back with another Excel issue. wondering if you know anything about it.<br><br>While attempting to save an Excel file that I rec'd from a reputable source, and a file that I was originally saving while it was in Downloads...I moved the file to another Document folder, and that appears to have caused an issue, which seems strange. Here's what the error message is saying:<br><br>"Errors were detected while saving '/Users/ericstitt/Documents/P..... Logs/WorkingBidPlus5thDay_LAT_09-26.xlsb'. Microsoft Excel may be able to save the file by removing or repairing some features. To make the repairs in a new file, click Continue. To cancel saving the file, click Cancel."<br><br>What do you think?
