It's more simple to to it step by step: 1- Your qes file has to contain a variable (string, length = 4. I call it YV1)) to store the year of the date entered in V1. 2- In the chk file, edit checkblock for V1, and add the line: YV1 = year(V1) 3- Then, it is possible to enter the check lines that will calculate the categories: If YV1 = "xxx" then CATEGORY = "xxx" Endif If YV1 = "yyy" then CATEGORY = "yyy" Endif (...) End (assuming there is a variable called Category!)
That's it. It's better (although you can do without) to add NOENTER to YV1 checkblock, so that it will be impossible to enter another value by accident.

I am having some difficulties playing around with a date variable (named v1, form dd/mm/yyyy). I wish to create a new variable with categories based upon different years within the original variable and I have tried copying the examples provided in the help section, but I'm not having any luck. Any direction would be greatly appreciated. Thanks, Kate
