Problem with Border

[hgu]

Hi,
I am new with this, so forgive me if this is very basic question.
I am using GuMaxV, and also use a calendar extension as well -- Extension:Calendar (Kenyu73).

Somehow, when i use GuMaxV, the borders on the calendar disappears between different days.

I did some tweaking but didn't help.
Can you tell me what I need to change to bring back the border?

thx

Han

View the source code of the page to see what tag around the calendar... then make changes in CSS file.
