InfoPath Dev

Using InfoPath 2003, trying to set the default value of a date picker field to +30days of another date field.  I cannot use code, must use XPATH or the field function (fx).

I tried something like:

 concat(msxsl:format-date(now(), "MM"), "/", msxsl:format-date(now(), "dd") + 30, "/", msxsl:format-date(now(), "yyyy"))

 but that didn't work: I does not roll over with the month and I'm getting 3/49/2012.

Any Help?

I doubt that there's a decent codeless way to do this in 2003.  Does it have to be 30 days?  Would just incrementing the month be sufficient?

30 days is policy.

 BUT, If I increment the month, I'll be right 1/3, right?  And it's only a default value --they will change it 90% of the time anyway.  Good Call.

 Thanks, we'll increment the month and see what the policy boys have to say...
