Userform - Want textbox row to clear itself after I move the coursor to another textbox

Hi!

I'm new and terrible at this , so forgive me if I don't really know how to describe my problem


I need my user form to clear the previous box I was in when I move the cursor to the next box
You can only enter data into the extreme left column , and it will fill out the rest of the row with the calculation
Currently it will look like this when I enter start entering numbers into another row

I want it to look like this
All numbers from the previous row disappear when I move the cursor to another box

Also , is it possible to change the default highlight color from light blue to yellow?
I have circled it in red

Lastly , is there a way to put this directly on worksheet itself?
Cause I have 3 of these tables and I can't open any other when one of them is opened
That was I can put one on each sheet and just use the tabs below to switch

Thanks for any help!
