How to use information from a ComboBox in another one? - excel

Question

I'm trying to make a UserForm with comboboxes and textboxes. I have two combobox that are working together. In the first one you choose the right sheet and in the second you choose the right column in the selected sheet.
My problem is that even though my code is working, the second combobox doesn't use the moving information from the first one. It always displays the columns from the first sheet whatever my choice. So how do I get the data from the first one to use it in the second one?
Here's my code:
Private Sub UserForm_Initialize()
Dim I As Long
Me.ComboBox1.Clear
For I = 7 To Sheets.Count
Me.ComboBox1.AddItem Sheets(I).Name
Next
Me.ComboBox1.Value = ActiveSheet.Name
Me.ComboBox2.Clear
Dim j As Integer
Dim puits As String
j = 3
Do While Worksheets(ComboBox1.Text).Cells(1, j).Value <> ""
Me.ComboBox2.AddItem Worksheets(Me.ComboBox1.Text).Cells(1, j).Value
j = j + 3
Loop
End Sub```
EDIT
[USF is to automate the change of the selected cell in this screenshort, same tables on different sheets][1]

You need to use the Combobox_Change-Event. This Example shows what I mean:
Private Sub ComboBox1_Change()
Dim ws As Worksheet
Dim lCol As Long, i As Long
Set ws = ThisWorkbook.Worksheets(UserForm1.ComboBox1.Value)
lCol = ws.Cells(1, ws.Columns.Count).End(xlToLeft).Column
For i = 1 To lCol
UserForm1.ComboBox2.AddItem ws.Cells(1, i).Value
Next
End Sub
Private Sub UserForm_Initialize()
Me.ComboBox1.Clear
Me.ComboBox2.Clear
Dim ws As Worksheet
Dim i As Long
i = 1
For Each ws In ThisWorkbook.Worksheets
Me.ComboBox1.AddItem ws.Name
i = i + 1
Next ws
End Sub
When I select the Sheet, I change the first Combobox, which triggers the Change-Event. And I then populate the second Combobox according to the selected sheet.
EDIT
You could insert a CommandButton and use code like the following:
Private Sub CommandButton1_Click()
Dim ws As Worksheet
Dim rng As Range
Set ws = ThisWorkbook.Worksheets(UserForm1.ComboBox1.Value)
Set rng = ws.Range(UserForm1.ComboBox2.Value)
rng.Value = "Your Date"
End Sub
