How do I show the company name to which a 'Call' is scheduled on my home page?

How do I show the company name to which a 'Call' is scheduled on my home page?

Hi everyone - hope that this is a simple problem and I can use Zoho as intended as currently it's not working for me properly yet!
This is one of the eproblems I have encountered and I have looked at 'map dependency' with no success - maybe I'm missing something that's obvious to other more experienced users? I have attached a screen shot to illustrate what my issue is a little better (I hope!)

Any help greatefully received.

Many thanks in advance to any/all that can help here :)

Kind Regards
