VBA copy rows that meet criteria to another sheet

Question

I am new to VBA...I want to copy a row from Sheet2 to Sheet1 if the first cell in this row says X and then do so for all the rows that meet this criteria. I have an error in the If condition...I don't know how to fix it.

Sub LastRowInOneColumn()
'Find the last used row in a Column: column A in this example
    Worksheets("Sheet2").Activate
    Dim LastRow As Long
    With ActiveSheet
        LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
    End With
    MsgBox (LastRow)
    For i = 1 To LastRow
    If Worksheet.Cells(i, 1).Value = "X" Then
    ActiveSheet.Row.Value.Copy _
    Destination:=Hoja1
    End If
    Next i
 End Sub

Answer 1

You need to specify workseet. Change line

If Worksheet.Cells(i, 1).Value = "X" Then

to

If Worksheets("Sheet2").Cells(i, 1).Value = "X" Then

UPD:

Try to use following code (but it's not the best approach. As @SiddharthRout suggested, consider about using Autofilter):

Sub LastRowInOneColumn()
   Dim LastRow As Long
   Dim i As Long, j As Long

   'Find the last used row in a Column: column A in this example
   With Worksheets("Sheet2")
      LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
   End With

   MsgBox (LastRow)
   'first row number where you need to paste values in Sheet1'
   With Worksheets("Sheet1")
      j = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
   End With 

   For i = 1 To LastRow
       With Worksheets("Sheet2")
           If .Cells(i, 1).Value = "X" Then
               .Rows(i).Copy Destination:=Worksheets("Sheet1").Range("A" & j)
               j = j + 1
           End If
       End With
   Next i
End Sub

Answer 2

After formatting the previous answer to my own code, I have found an efficient way to copy all necessary data if you are attempting to paste the values returned via AutoFilter to a separate sheet.

With .Range("A1:A" & LastRow)
    .Autofilter Field:=1, Criteria1:="=*" & strSearch & "*"
    .Offset(1,0).SpecialCells(xlCellTypeVisible).Cells.Copy
    Sheets("Sheet2").activate
    DestinationRange.PasteSpecial
End With

In this block, the AutoFilter finds all of the rows that contain the value of strSearch and filters out all of the other values. It then copies the cells (using offset in case there is a header), opens the destination sheet and pastes the values to the specified range on the destination sheet.
