I need a timer process to run in seconds that will either mimic closing and opening a workbook without actually closing and reopening as this is currently the only way a formula updates from an add-in or do a loop to change the formula by deleteing the &quot;=&quot; and addit it back. &nbsp;Formula would be =(a:1+b:2) for example.
