Copy and paste VBA code - I want to use across multiple sheets - vba

Question

I'm very new to VBA. I have some code that will copy data that meets a certain criteria in one sheet to another master sheet. I have multiple other worksheets that I want to copy from into the master. How do I amend my code to do that please?
Thanks in advance.
Sub copyPaste()
Dim ws As Worksheet
Dim wt As Worksheet
Set ws = Sheets("S_Q")
Set wt = Sheets("master")
Dim i As Integer
Dim lr As Integer
lr = ws.Range("y" & Rows.Count).End(xlUp).Row
Dim lt As Long
For i = 1 To lr
lt = wt.Range("y" & Rows.Count).End(xlUp).Row
If ws.Range("bz" & i) > 14 Then
ws.Range("y" & i).EntireRow.Copy wt.Range("a" & lt + 1)
End If
Next i
End Sub

Without diving too far into the specifics of your code itself - will the criteria be the same for all worksheets you're wanting to run it on? And is the layout of the data in all of those worksheets?
If so, and if your current code is doing what you need it to do for Worksheet A and we just need to expand that to also handle Worksheets B through X, then you could get rid of your dim/set ws lines, and instead change your first line to
sub copyPaste(ws as worksheet)
This would allow you to then use a separate procedure to call this procedure for each of your worksheets that it needs to be run on. Below is an example using the worksheet from your original code:
call copyPaste(ThisWorkbook.Sheets("S_Q"))

I would put the sheets of interest to loop over in an array and loop that. I would also use Union to gather the qualifying ranges and paste in one go to be more efficient.
I would also use a helper function to retrieve the last row and add one to that to get next row.
Also, use Long rather than Integer to avoid potential overflow as there are more rows in a sheet than Integer can handle.
Option Explicit
Public Sub copyPaste()
Dim ws As Worksheet, wt As Worksheet, sheetsOfInterest(), unionRng As Range
Dim i As Long, lastRow As Long, lastRowMaster As Long
Application.ScreenUpdating = False
sheetsOfInterest = Array("Sheet1", "Sheet2", "S_Q")
Set wt = ThisWorkbook.Worksheets("master")
For Each ws In ThisWorkbook.Worksheets(sheetsOfInterest)
lastRow = GetLastRow(ws, 25)
For i = 1 To lastRow
If ws.Range("BZ" & i) > 14 Then
If Not unionRng Is Nothing Then
Set unionRng = Union(unionRng, ws.Range("bz" & i))
Else
Set unionRng = ws.Range("BZ" & i)
End If
End If
Next i
If Not unionRng Is Nothing Then
With wt
unionRng.EntireRow.Copy .Range("A" & GetLastRow(wt, 1) + 1)
End With
End If
Set unionRng = Nothing
Next
Application.ScreenUpdating = True
End Sub
Public Function GetLastRow(ByVal ws As Worksheet, Optional ByVal columnNumber As Long = 1) As Long
With ws
GetLastRow = .Cells(.Rows.Count, columnNumber).End(xlUp).Row
End With
End Function

After trying the filter on various columns and it working on some and not others; with no apparent reasoning. I decided to rejig the spreadsheets and put the column to be filtered in the first column. This seems to be working so far.
