VBA check value from column A exists in another wo

I am trying to build a macro that loops through a range of values within colA and check if they exist with another workbook. In one of them I would like to mark it "Worked"/"Not Worked"

Any guidance on where to start?

Example

Here is an example of what you're looking for. Remember that both the workbooks have to be opened in the same instance of Excel.

Sub check()

Dim i As Integer, k As Integer, j As Integer 'Define your counting variables
Dim Report1 As Worksheet, bReport As Workbook, Report2 As Worksheet, bReport2 As Workbook 'Define your workbook/worksheet variables

Set Report1 = Excel.ActiveSheet 'Assign active worksheet to report1
Set bReport = Report1.Parent 'Assign the workbook of report 1 to breport


On Error GoTo wbNotOpen 'If an error occurs while accessing the named workbook, send to the "wbNotOpen" line.
Set bReport2 = Excel.Workbooks("otherworkbookname.xlsm") 'Assign the other workbook which you are cross-referencing to the bReport2 variable.
Set Report2 = bReport2.Worksheets("otherworksheetname") 'Do the same with the worksheet.
On Error GoTo 0 'Reset the error handler (to undo the wbNotOpen line.)

k = Report1.UsedRange.Rows.Count 'Get the last used row of the first worksheet.
j = Report2.UsedRange.Rows.Count 'Get the last used row of the second worksheet.

For i = 2 To k 'Loop through the used rows of the first worksheet. I started at "2" to omit the header.
    'Next, I used the worksheet function "countIf" to quickly check if the value exists in the given range. This way we don't have to loop through the second worksheet each time.
    If Application.WorksheetFunction.CountIf(Report2.Range(Report2.Cells(2, 1), Report2.Cells(j, 1)), Report1.Cells(i, 1).Value) > 0 Then
        Report1.Cells(i, 5).Value = "Worked" 'If the value was found, enter "Worked" into column 5.
    Else
        Report1.Cells(i, 5).Value = "Not worked" 'If the value wasn't found, enter "Not worked" into column 5.
    End If
Next i




Exit Sub
'This is triggered in the event of an error while access the "other workbook".
wbNotOpen:
MsgBox ("Workbook not open. Please open all workbooks then try again.")
Exit Sub

End Sub

This link also includes steps that tell how to check if a cell exists in another workbook. The comments are useful.

Thanks to #Lopsided's solution, I have tweeked his code to bring forth this solution. And this seems to work.

{       
Sub CheckValue()

Dim S1 As Worksheet
Dim S2 As Worksheet

Dim i As Integer
Dim k As Integer
Dim j As Integer

Set S1 = Worksheets("Sheet1")
Set S2 = Worksheets("Sheet2")

k = S1.UsedRange.Rows.Count
j = S2.UsedRange.Rows.Count

For i = 1 To k
If Application.WorksheetFunction.CountIf(S2.Range(S2.Cells(2, 1), S2.Cells(j, 1)), S1.Cells(i, 1).Value) > 0 Then
    S1.Cells(i, 5).Value = "Worked" 'If the value was found, enter "Worked" into column 5.
Else
    S1.Cells(i, 5).Value = "Not worked" 'If the value wasn't found, enter "Not worked" into column 5.
End If
Next i
End Sub

}
