Hello, I am have very little knowledge in VBA.

I am creating a form for the company I am working for.
I am using a content control user forms

I have a combo box (Title/Tag : Doctor)

After selecting a choice, I want a text content control (Phone) to autofill the information

Someone have suggested using a change Event Handler, but I do not know how to do this. If someone can help me with this I appreciate it

Thank You
