[Zope] Python syntax error

[Julian Clark]

Hi list...
I'm getting a bizarre set of syntax errors.

I've a python script which I call from a dtml method.

This script works

today=DateTime()
day=today.dd()
month=today.Month() 
year= " 20"+today.yy()
string= day + ' ' + month + year
return string

when I modify it to something like this..
today=DateTime()+7
day=today.dd()
month=today.Month() 
year= " 20"+today.yy()
string= day + ' ' + month + year
return string

I get a syntax error.

Any suggestions?

here's the traceback
