I have a task list that works very well... we each create tasks for each other, when a task is done we check complete and it no longer shows on the list based on a find script.

But now, I would like to add a date field, so that you can have the task not be found on the list for a time, but then be found later, for example: the task "disappears" to the user for a day, then it "shows up" on the list again the next day as a reminder to followup. But all the other tasks still need to show indefinitely until they are marked completed.

What is the best way to make this happen?

I am already using a refresh button to run the script, so I am assuming it would be best to use a script to accomplish this.

You would need to use a creation date (auto-enter creation date) which you should have anyway. Then your script to find records not complete would be adjusted as:

Enter Find Mode [ uncheck pause ]

Set Field [ Complete ; "=" ]

Set Field [ CreationDate ; "<" & Get ( CurrentDate ) ]

Perform Find [ ]

UPDATE: If you wish to control how many days the task doesn't appear, use a global field called gDays and adjust the calculation as:

"<" & Get ( CurrentDate ) - gDays

Great! I'll try that and let you know how it works.
