Small change to your code below. Will that work? Jamie

I am hoping I can get some help with epidata and use of year and week.

Before file DEFINE WEEKS ## DEFINE YEARS #### DEFINE WEEK ####.## end DATEFROM MUSTENTER AFTER ENTRY LET WEEKS = WEEKNUM(DATEFROM) + 1 LET YEARS = YEAR(DATEFROM) LET WEEK = float(YEARS)+float(WEEKS)/100 END END

If you want WEEK as a string, try:

let week = string(years)+"-"+copy(string(100+weeks),2,2) (week is a string of length 7) This will yield WEEK like the following "2006-01" "2006-52"
