A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Maybe try putting ticker (e.g. XLON:ITPS) into what you know to be a blank cell as text , select cell , then click STOCKS - if that works it might be a case of reformatting the cells with ?'s in as text, enter the text string (e.g. XLON:ITPS) and the click STOCKS on just that highlighted cell. It's working for me so far fingers crossed.
