Display Value of Cells into Text Box using a Command button

Hi, I'm new in VBA programming and I need help in creating a simple inventory.

REQUIREMENTS:
> When I enter the printer model and click the SEARCH button, it will display the available stocks of toners for that particular model (C, M, Y and K)
> There is a button to UPDATE the stocks.(when new supplies will be delivered)

A sample of the list is attached. I hope someone can help me with this. Thank you in advance.
