Track Changes of a Date Field

np,

in the email just use the syntax 

[old.date] to refer to the previous value at the split second before the save.  Quickbase will remember that value just long enough to send off the email.

You can also use field references to capture the original value from a field (before it was changed) and display it in an email.

To do so, type old. in front of the field name, as in [old.status] or [old.description] for example. For example, say you've inserted the following custom text in your notification:

The city changed from [old.city] to [city].

If a user were to change the value in the city field from Boston to Paris, this line would display in an email as:

The city changed from Boston to Paris.
