Insert Values in Multiple Cells

[Pinkster69]

Hi Guys,
Hope you can help me out with a problem I am having, still fairly new to VBA!

I have a User form with a ComboBox "SKUNumberComboBox" which has a list of SKU Numbers and I have a Date Picker "DTPicker1" were I can pick a date and I also have a TextBox "ExtraDaysTextBox" were I enter the amount of Days.
Basicly when I enter the SKU Number in the "SKUNumberComboBox" and the Date from the "DTPicker1" and I enter a Value of lets say "8" in the "ExtraDaysTextBox" I have code finding the Cell that intersects between the Value in the SKUNumberComboBox" and the "DTPicker1" and from this cell I need to enter the number "1" in the "8" Cells on that row after that with respect to the value in the "ExtraDaysTextBox" which is "8".
I attached the code I have so far so I hope you can help me??

Const DataSheet = "Data"        ' Sheet with data
Const HatDates = "F2:AWG2"      ' Address of dates
Const HatSKUs = "A2:A1000"       ' Address of SKUs
Const FLAG = 1                  ' flag

Private Sub SetFlag()    ' Set flag in table, enters the number "1" in the appropriate cell
    
    On Local Error GoTo errors
    
    'Looks for the Cell with referance to the SKU and the Date and enters "1"
    With Sheets(DataSheet)
        Set DateFound = .Range(HatDates).Find(what:=DTPicker1.Value)
        Set SKUFound = .Range(HatSKUs).Find(what:=SKUNumberComboBox.Value)
                
        .Cells(SKUFound.Row, DateFound.Column) = FLAG           'Enters "1" in the Cell corrosponding to DTPicker1.Value & SKUNumberComboBox.Value
        
       
             
    End With
Exit Sub


errors:
    MsgBox "Error: " & Err.Description


End Sub
