A Control Source is a reference to a worksheet cell linked to the
TextBox field on your UserForm.

You can type in a cell address (use a sheet reference) or with a cell
name. Once you enter the reference to the worksheet, what you type in
the UserForm TextBox will appear in the

Be aware that a Control Source will overwrite the value in the cell,
even if it is a formula. (That is, if you enter a formula into the
linked cell, the UserForm text box will show the value in the UserForm
TextBox. However, once you view the value in the UserForm, the formula
will be replaced with it's value only.)

Play with it a few times on a test sheet...
