Hi,

I would love some help!
I try to copy the personal tax in 2002 to all years.

My initial data looks like this:

Year ID Tax

2001 1 .
2002 1 0.2
2003 1 .
2001 2 .
2002 2 0.14
2003 2 .
2001 3 .
2002 3 0.25
2003 3 .

The prefered outcome looks like this:

Year ID Tax

2001 1 0.2
2002 1 0.2
2003 1 0.2
2001 2 0.14
2002 2 0.14
2003 2 0.14
2001 3 0.25
2002 3 0.25
2003 3 0.25


I really appreciate any help you can provide.
