My loops seems to be filling information even if a match isn't found

Question

I have the loop below that I use to find information in another sheet and fill into the one I'm working on. I would like the loop to not update if a value isn't found. However it seems to update with the line above and I can't figure out why. Your help would be greatly appreciated.

updrng1 is the cell I'm using for my loop and WorkRng1 is the range for my current sheet I'd like updated WorkRng2 is the range that the identifier in WorkRng1 I'm looking for a match

Public variables:

Option Explicit
Public WorkRng1 As Range
Public WorkRng2 As Range
Public WorkRng3 As Range
Public Rng1 As Range
Public Rng2 As Range
Public Rng3 As Range
Public blkRow As Range
Public subTskRng As Range
Public UOMRng As Range
Public nmbrRng As Range
Public unitCostRng As Range

This is my form code:

Private Sub CommandButton1_Click()
Dim updRange1 As Range

Set updRange1 = Application.InputBox("Please select all Tasks ID Cells you would like to update", "Title", Type:=8)
Application.ScreenUpdating = False

updRange1.NumberFormat = "@"

Dim matchCounter As Integer
matchCounter = 0

Dim FoundRange As Range
    For Each updrng1 In updRange1
    ''tests task exists in work range 2
    WorkRng2.Parent.Activate
    If updrng1 <> 0 Then
        Set FoundRange = WorkRng2.Find(what:=updrng1.Value, LookIn:=xlValues, LookAt:=xlWhole)
        If FoundRange Is Nothing Then
            MsgBox "test" & updrng1
        Else
    'updates subtask info
            WorkRng2.Find(what:=updrng1.Value, LookIn:=xlValues, LookAt:=xlWhole).Select
            If Cells(ActiveCell.Row, subTskRng.Column) <> 0 Then
                Cells(ActiveCell.Row, subTskRng.Column).Copy
            Else
                Cells(ActiveCell.Row, subTskRng.Column - 1).Copy
        End If
        WorkRng1.Parent.Activate

        End If

With the help of everyone in the comments I was able to get the code below working. Bonus: I even added in a mismatch error counter that displays the array in a txtbox.

For those interested here is my working code:

Private Sub CommandButton1_Click()
Dim updRange1 As Range
Dim list As String
On Error GoTo Whoa
Set updRange1 = Application.InputBox("Please select all Tasks ID Cells you would like to update", "Update Range", Type:=8)
Application.ScreenUpdating = False

updRange1.NumberFormat = "@"

Dim matchCounter As Integer
Dim errorCounter As Integer
matchCounter = 0
errorCounter = 0
Dim FoundRange As Range

    For Each updrng1 In updRange1
    ''tests task exists in work range 2
    WorkRng2.Parent.Activate
    If updrng1 <> 0 And updrng1 <> "Sub Total - Labor Fees" And updrng1 <> "Sub Total - Meetings" And updrng1 <> 21 Then
        Set FoundRange = WorkRng2.Find(what:=updrng1.Value, LookIn:=xlValues, LookAt:=xlWhole)
        If FoundRange Is Nothing Then
            list = list & updrng1 & ", "
            errorCounter = errrorCounter + 1
        Else
    'updates subtask info
    If Me.txtSubTask.Value <> 0 Then
            WorkRng2.Find(what:=updrng1.Value, LookIn:=xlValues, LookAt:=xlWhole).Select
            If Cells(ActiveCell.Row, subTskRng.Column) <> 0 Then
                Cells(ActiveCell.Row, subTskRng.Column).Copy
            Else
                Cells(ActiveCell.Row, subTskRng.Column - 1).Copy
