Macro that runs when a sheetname in a file does not exist

Hi Guys!

I am looking for a solution to a problem i'm facing in the code below I want to import data from a file if the file name contains "Test". If the filename contains "Test" VBA should unprotect the sheets and look for a sheet called "Check test".

This is where the problem starts. Not every file called "Test" has a sheet called check test. I would like the macro to move on to the next workbook (and preferably give a message) if this sheet does not exist in the file. Please help out!!

Sub Test_import()

Dim wb As Workbook
Dim wbName As String
Dim Password As String
Dim ws As Worksheet
Dim activewrkbook As Workbook
Dim lSecurity As Long

'Change this line if you want to activate workbooks with a different name that are opened
wbName = "test"
Password = "DUMMY"

Application.ScreenUpdating = False


Workbooks("Certificates file.3.xlsm").Activate

'Start of the For Each loop that checks all opened workbooks containing "wbName"
For Each wb In Application.Workbooks
   
    

                
            If LCase(wb.Name) Like "*" & wbName & "*" Then
                    Debug.Print wb.Name
                    wb.Activate
                                        
                Application.DisplayAlerts = False
            
                Set activewrkbook = ActiveWorkbook
                
            'When there's an error go to the bottom error message
            'On Error GoTo errormsg
       
                    'On Error Resume Next
                    ActiveWorkbook.Unprotect Password:=Password
                    
            'Protect each sheet in the active workbook
                For Each ws In ActiveWorkbook.Worksheets
                    
                    ws.Unprotect Password:=Password
                Next ws
