VBA to sum column with particular header and capture in a master file

Question

I have the below code that, when pointed at a particular folder, will capture the following data in my check tab : file name, number of rows, number of columns. The final part i need help with is to find a header, say its "value", and sum the column, posting the total adjacent to each file name starting in cell d8. Code below. Any ideas how to do this easily?

    Sub CollectData()

    Dim fso As Object, xlFile As Object
    Dim sFolder$
    Dim r&, j&, k&
    
    '*
    Sheets("Check").Activate
    Range("F8:I50").ClearContents
    Range("A8:D50").Copy Range("F8")
    Range("A8:D50").ClearContents
    
    '*
     
    With Application.FileDialog(msoFileDialogFolderPicker)
        .AllowMultiSelect = False
        .InitialFileName = ThisWorkbook.path
        If .Show Then sFolder = .SelectedItems(1) Else Exit Sub
    End With
    Set fso = CreateObject("Scripting.FileSystemObject")
    For Each xlFile In fso.GetFolder(sFolder).Files
        With Workbooks.Open(xlFile.path, Password:="password")
            With .Sheets(1)
                j = .Cells(.Rows.Count, 1).End(xlUp).Row
                k = .Cells(1, Sheet1.Columns.Count).End(xlToLeft).Column
                             
                               
            End With
            .Close False
            
        End With
               
        r = r + 1
        Cells(r + 7, 1).Value = xlFile.Name
        Cells(r + 7, 2).Value = j
        Cells(r + 7, 3).Value = k
                
    ActiveWorkbook.Save
       
    Next
         

End Sub

I would just iterate over the header cells and check for cell.value:

Dim headers As Range
Dim c As Range
Dim SumRange As Range
Dim Sum As Double

    Set headers = Range("F8:I8")
    
    For Each c In headers
    
        If c.Value = "value" Then
            'From the header, go 1 cell down and get range of continous non blank cells
            'Set the SumRange variable to this range of cells
            Set SumRange = Range(c.Offset(1, 0), c.End(xlDown))
        
        End If
    
    Next
    
    'Iterate over the SumRange cells, and add to Sum variable as you go
    For Each c In SumRange

        Sum = Sum + c.Value

    Next
    
    'Display Sum in destination cell
     Cells(r + 7, 4).Value = Sum
