Formatting query, incremental values with leading zeros

Hi all,

I'm tracking weeks by weeknumber in the format YY-WW. At the moment I am entering the weeks manually in a general cell, preceeded by a '. I would prefer to have the sheet work out the weeks for me as we move the sheet every week. I would like to format the initial cell as follows:

09-08 (or '09-08 if I must)
then have the next cell in sequence read 09-09, 09-10, and so on. With the initial week in cell A3, I have tried to accomplish this with:

=LEFT(A3,3)&RIGHT(A3,2)+1

However, this does not work for weeks 01 through 09 because excel kills the leading zero in the second part of the formula, regardless of how I format the cell (format 00-00 does not work.) How can I force Excel it to keep the leading zero in the week number?

Suppose your data is in Row A ......


=RIGHT(YEAR(A1),2)&"-"&WEEKNUM(A1,2)

=left(aA3,3)&text(right(A3,2)+1,"00")
