Mihail:
In the cross posted thread it is "asked and answered"
So it would be helpfull for you to restate the question.
I noticed in the cross-post that there was a little confusion about what you were/are after; thus, by restating/rephrasing the question a fresh view might be established.
As for what I've been able to follow, from this link:
Set default values for fields or controls (ACC2007/2010) you should be able do what you ask about.
So, re-phrase, show your work (^-^), and as usual we'll give it the best effort
