Is it possible to do that using a Listbox Form?

Hi everybody!

I'm new user in forum, and I'm from Brazil, so I'd like to ask apologize for any english mistakes.
I've already searched for this solution in some brazilians forum, but no one knew how to help me or even answered my questions.

So, if you guys cou help me, I'd greatly appreciate it.

Follows my questions:

1 - Open file, according the hyperlink on the "BD_Assessoria" sheet, through the listbox.

2 - Is there any way to open the listbox by clicking over the cells who is written "1" or "2 Publicaçoes"? Is it possible to assign a macro to the filled cells, or maybe something like that? However, I'd like to open only the publications related to that calendar date.
For example: If we select January, we have publications on days 30 and 31. At 30th, we've 2 publications. I'd like to open a listbox form to choose one between those 2 publications and open the selected file.

3 - In case number 2 above isn't possible to do, I'd like to open the publications according to month and day selected at the combo box, in the left corner of the calendar. For example, by selecting January, then day 30, click over the button "Exibir Publicaçoes" and open the listbox, through this filters.

I need to present this work for my directors, and I'd be very grateful if you guys could help me!

Cya.
