How to use variable in DateAdd function

Hi,

In CBTA

I initialized a variable(V_DATE) with current date using expression-

%=day(now)&"."&month(now)&"."&year(now)%

Then I want to add 1 to day,so I used the below expression-

%=DateAdd("d",1,$V_DATE$)%

But the DateAdd function is not working.

Can anyone tell me how to use variable(V_DATE) in DateAdd function.

Thanks in advance for your help
