Excel Textbox
 

I am creating a calendar using a template from Microsoft Excel and I am
trying to create a textbox by using a formula. I want to have two sheets,
one with the dates and what I am doing on that data and one with the
calendar. In the box for a particular day I want to place a formula to open
a textbox that has the information from the previous sheet.

Basically, is there a formula to create a text box?
