Color Rows Where To/From Row Numbers Reside In 2 TextBoxes

I am currently trying to make some VB code that will allow me to offset and select cells depending on a couple of variables.

I have a UserForm that requires two numbers from the user. These numbers will correspond with the cells I want to highlight (the strings from the TextBoxes in the UserForm are called 'test1' and 'test2' in the code shown below)

Dim test1 As String
Dim test2 As String

Private Sub CommandButton1_Click()
test1 = Roww1.Text
test2 = Roww2.Text

Worksheets("Sheet2").Range("A1").Value = test1
Worksheets("Sheet2").Range("B1").Value = test2

When this script is run, I want to end up with some selected cells in sheet1 that match up with the numbers the user enters into the UserForm.
