[Zope] using expr inside sendmail

[Mike Doanh Tran]

Hi,

Assume A=5, B=3, and C=2.
when I use this expression outside of the <dtml-sendmail> tag then I get a 
Total="10"

Total = <dtml-var expr="A+B+C">

But when i use the above expression inside of <dtml-sendmail> </dtml-sendmail>
I get the value of A,B,and C (5 3 2)

I just want to send out the grand total of A,B, and C.
What is wrong with my syntax? Can someone help please?

Thanks,
