Dear Experts,

Normally, I use the evaluate formula to see how the calcs are performed.
However, there is a program that was created using Visual Basic. I am not
able to see the calculations behind it. How do I access this?

I have the password to get into this program via Visual basic editor but I
all I see is VB language etc.

Is there a way I can see the figures being calculated?
Kind Regards

Ed
