Vba to exit sub on cancel on inputbox

I have a macro to copy a template and rename the new sheet after what user puts in inputbox.
If you put nothing and press OK or if you press Cancel I get error: application defined or object defined error.

What I would like is: if you put in nothing and press OK or if you press Cancel to exit sub and of course delete the sheet it copied and maybe a msg that nothing happened.
I tried if ... "false" and some other stuff but nothing worked.

This is my code:

I put in my msgbox as well.
