Comportament neașteptat de "Pentru Fiecare wks În ActiveWindow.SelectedSheets", aceasta afectează mai mult coloană care ar trebui să fie

am făcut acest cod care funcționează destul de bine, afară de ultima parte:

Comportamentul din ultima parte ar trebui să fie ".Interior.Culoare" și ".Valoarea" a afectat până în ultima populate coloană, în loc să-l afectează în prima celulă de multe alte coloane. Orice idei?
