Found a workaround to this with c#, but i don't know how to include my own variable to the c# code:
int month = 10;
int year = 2013;
int numberOfDays = DateTime.DaysInMonth(year, month);
DateTime lastDay = new DateTime(year, month, numberOfDays);
return lastDay;
Changing red part to 'project.Variables["month"].Value' how it's described by
Hungry Bulldozer Here does not compile/work.
I want to include my variable in the red part of the code.
Can i?
