Yes, thank you. It now works.
On my iPhone I had to sign in to my Apple ID in send and receive (Small box at top asking me if I want to use my Apple ID) to have a choice to use my Apple ID under send and receive.
I hadn’t done this because I didn’t want to use my Apple ID to receive text messages.
This apparently caused my phone number to appear on my iPad “Send and Receive“ section so I could check The phone number as my choice.
On my iPhone, under messages, I had to turn on the iPad switch under text forwarding to make the iPad receive.
i hope this makes sense.
Thank you for your help!
