Daily record from dymamic table

Hello
I'm using a dynamic table. At the end of the day I need to record a value from this dynamic table in a different table manually. The next day the values can change and I repeat the step.
How can I do this in an automatic way without doing copy paste each day?
Thanks

Hi and welcome
if the new value replaces the old one, a simple formula like =A1 would suffice?
Perhaps some more information would help?

No...I need to have the old value...
Day 1: 345
Day 2: 346
Day 3: 456
Thanks
