Mouse roll over View

Hi there,

Need help in one of the complex file where we have number of Heads present month wise and designation wise. Synopsis is created in front for all these users. Now requirement is that we have numbers in synopsis..

i.e. Jan - 2 Headcounts, Feb - 4 Headcounts. Once I click on these numbers or roll over the mouse, it should show the names on screen (Like screen tip).

I have attached sample file please help.

Thank you.
