Comparing columns in two different excel sheets and workbooks, then posting the matching value into another column

Question

I'm having lots of trouble trying to figure out this macro, so right now I'm using 2 sheets in a workbook; I'd like to use two different workbooks but that isn't as important as the issue.

To explain, Sheet1 column E is the id number and in Sheet2 column A is the id number, now if any value in Sheet1 E matches a value in column A in Sheet2, I need the macro to copy the corresponding cell from Sheet 2 column D. So essentially if E5 (from sheet 1) matched A1 in Sheet2, I would need the macro to output Sheet2's D1 to Sheet1's F5. It would also be nice to delete the values of Sheet1 column F if Sheet1 column E doesn't match a value in Sheet 2 column A.

I have some code but it just pastes the values from Sheet2's column D if a value of Sheet1 column E matches a value from Sheet2 column A. The problem is when the values pasted from Sheet2 are pasted in Sheet1's column F and the values aren't matched with the correct value that it matched with in Sheet2. They are just dumbed. So if Sheet1 column E was like this

Sheet1 Column E    Sheet1 F

1317               relays_120x120.jpg
1319              Control%20boards_120x120
1320              Control%20boards_120x120

Sheet2 Column A             Sheet2 column D
1317                       relays_120x120
1318                       /relays_120x120
1319                    ebay/SingleRunOval

But in reality I need them all to be equal and if Sheet1 column E has a value that isnt in Sheet2 column, then dont post a link in Sheet1 column F leave it blank.

Here is the code I have

Sub FindMatches()

    Dim oldRow As Integer
    Dim newRow As Integer
    Dim i As Integer

    i = 1

    For oldRow = 2 To 1170
        For newRow = 1 To 1170
            If Worksheets("Sheet1").Cells(oldRow, 5) = Worksheets("Sheet2").Cells(newRow, 1) Then

                Worksheets("Sheet1").Cells(i, 6) = Worksheets("Sheet2").Cells(oldRow, 4)


                i = i + 1

                Exit For
            End If
        Next newRow
    Next oldRow


End Sub

Sounds like you could accomplish your goal with the VLookup function. Add this formula to Sheet1 F1: =IFERROR(VLookup(E1,Sheet2!A:D,4,FALSE),"")

That formula will copy the cell into sheet1 if a match is found, but if no match is found the cell will remain blank.
