Default value with expression doesn't work

I have a problem to set default value with expression like..
=DateSerial( Year(Now), Month(Now) +1, 0).
I try with Today, Globals!ExecutionTime,..but it doesn't work.
In preview and on server parameter filed is disabled. If i press View Report
then fileld gets correnct value. To view report i must press view report
again.
Thanks.I found the problem, but not the solution..
The problem arise when i have multiple parameters with 'expression' default
value.

We do not know if expression depends on other parameters, therefore
expression is evaluated only when values of all preceding parameters are
known.
The workaround is to use default value from query.

Month(Now) +1, 0) it works fine, i get correct value.
If i have two or three there is a problem?
