What I am trying to do is I have a Index sheet, then other sheets for the jobs... On the Index sheet, I am displaying the Last Contact date we have contacted the manufacture, and I want to sort on the Index Page the last time I have contacted someone for the longest time and I will need to contact the customer...

I extracted the date by this formula to the index "=INDIRECT("H606-42!B3")" , I have a sheet called "H606-42" and taking info from line B3 , and it displays on the Index page.

On the index page, is there a Way I can filter the a section (Which I made 'Last Time Contacted' ) and filter by last known Date , but aswell, I cannot have the index Page changed... only temperately changed one section to see when was the last time I contacted the customer
