Hi Klaus,
I thank you again for your time.
The problem I have is that particular sub 'textbox1_lostfocus', it works only on desktop. As you can see on my [remarks] on that sub. This is why I have created the hidden textbox2 to make it worked on device. I don't know what are better solutions.
I have taken your additional code line and for desktop inputing could be lot easier using one of door library features that you could type directly on cells.

I agree on your suggestions and probably implemented on my future updates.

I have attached the CalcTable1.2desktop version for easier coding of formula on desktop also another sample conversion I've put together.

Thank you and best regards,
