Excel Cell Manipulation in Form

Hello, Im new to programming and would like some help please

I have successfully imported my excel into datasetview in a form. My question is now how do i manipulate each cell individually to do what i want to achieve?

An over simplified example: On another tab, i would like to have multiple buttons and each button assigned a textbox. By clicking button 1, i would like to find the mean of cells C2 & D2. Button 2 would do another function, button 3 another function etc..

This is an over simplified example, in reality i need to use each cell independently as well as a row. Some cells have letters only, some numbers only, and some have both.

Thanks for the help!
