DateAdd

Trying to use the DateAdd feature so I can do some MTD/YTD
comparisons. When I use the Expression builder, I am getting errors.
Using =DateAdd(yy, -1, 'parameter'), the yy is underlined in red.
I've tried year and Year. I've even seen it put into quotes ("yy").
I'm basically just trying to take the current date and subtract 1 year
from it. My ultimate goal is to create a report where I get LYTD/YTD
and MTD compared to the same month a year ago. This would key of a
report parameter since the user may want to look at particular month,
not just current. The report works fine as long as you manually put
in every date. I just need the DateAdd to make some automatic
calculations for me. Thanks in advance.On Dec 5, 3:51 pm, Barry <ba...@.tecelectric.com> wrote:

DateAdd is very finicky, and the documentation is really poor. It's
case sensitive, and only certain combinations seem to work. You will
want to use yyyy for Year, M or m for Month, d for Day, H for hour, n
for Minute, s for Second.
You want to not use the double quotes when you are using the function
in SQL, but do use the quotes when it is in a .Net expression.
1 Year Ago from Date
= DateAdd( "yyyy", -1, Parameters!CurrentYearsDate.Value )

PERFECT!!! I have spent many numerous hours searching for the correct
syntax. Worked great! Thanks so much.
