Need to translate code so i can tweak it

Someone helped me with some vba code and now i need to tweak the workbook which will require tweaking the code a little. Can someone translate the following code for me so i can learn what it is doing and then modify it for the changes? i am just learning VBA and am on a short timeline on this project for my boss. I can figure part of it out but not everything. Thank you so much for any help provided.

Sub test()
With Sheet1
For I& = 1 To .Cells(Rows.Count, 15).End(xlUp).Row
.[C9] = .Cells(I, 15).Value
.Range("A1:H47").PrintPreview
Next
End With
 
End Sub

Re: Need to translate code so i can tweak it

i haven't asked for help translating the code on another forum. I did get help creating the code on another forum. I saw a lot of people online on this forum late last night and thought i would get a quicker answer as a result. I will go back to the other forum and ask them. I would never deliberately waste anyone's time and i am sorry if anyone thinks that.
