IF, Then AND - problems with Syntax

Having some problems with Syntax. I have some experience with programming macros, but this doesn't seem to be working... what am I doing wrong? My goal is to compare 4 separate cell pairs in two different worksheets - if the 4 cell pairs are equivalent then one of the worksheets will be populated by another. Here is what I have. Any help would be greatly appreciated:

For k = 1 To x_last_row
    
    For i = 1 To y_last_row
     
  If
  
  Worksheets("X").Cells(k, 4).Value = Worksheets("Y").Cells(i, 2).Value And
  Worksheets("X").Cells(k, 11).Value = Worksheets("Y").Cells(i, 3).Value And
  Worksheets("X").Cells(k, 13).Value = Worksheets("Y").Cells(i, 4).Value And
  Worksheets("X").Cells(k, 7).Value = Worksheets("Y").Cells(i, 5).Value
    
  THEN
    
    Worksheets("Y").Cells(i, 87) = Worksheets("X").Cells(k, 1)
    Worksheets("Y").Cells(i, 88) = Worksheets("X").Cells(k, 2)
    Worksheets("Y").Cells(i, 89) = Worksheets("X").Cells(k, 3)
    Worksheets("Y").Cells(i, 90) = Worksheets("X").Cells(k, 4)
    Worksheets("Y").Cells(i, 91) = Worksheets("X").Cells(k, 5)
    
    
    End If

    Next i

Next k

I would use:

For k = 1 To x_last_row

For i = 1 To y_last_row

If Worksheets("X").Cells(k, 4).Value = Worksheets("Y").Cells(i, 2).Value _
And Worksheets("X").Cells(k, 11).Value = Worksheets("Y").Cells(i, 3).Value _
And Worksheets("X").Cells(k, 13).Value = Worksheets("Y").Cells(i, 4).Value _
And Worksheets("X").Cells(k, 7).Value = Worksheets("Y").Cells(i, 5).Value _

THEN

Worksheets("Y").Cells(i, 87) = Worksheets("X").Cells(k, 1)
Worksheets("Y").Cells(i, 88) = Worksheets("X").Cells(k, 2)
Worksheets("Y").Cells(i, 89) = Worksheets("X").Cells(k, 3)
Worksheets("Y").Cells(i, 90) = Worksheets("X").Cells(k, 4)
Worksheets("Y").Cells(i, 91) = Worksheets("X").Cells(k, 5)

End If

Next i

Next k

Note that you should add code tags as I have.

You should remember that you have to use " _" when you seperate two lines from one. Two below codes are same.

If a = b And a = c Then e = d

If a = b And _
     a = c Then e = d

Anyway, TMShucks helped you sloving your problem.
