Hello from Steved

Is the below possible please if so How would I go about it.

I Have a "input box", no matter where I'm on the worksheet I would like it
to open so the I can type ie 007,7.25 or something similar

I have this input box at the Beginning off the worksheet, and I find if I'm
on row 580 and I would like to open a input box on row 580.

I Thankyou.
