Periodically Copying Concatenated Data in Excel To Second Sheet While Primary Sheet Remains Active for Data Entry - vba

Question

I am pulling data from various cells on Sheet1 in Excel and copying the values to specific cells on a row in Sheet2 every specified period of time. I almost have my project completed but am unable to copy concatenated data in the same manner. How would I incorporate the following excel statement into my code for the data to be copied on sheet2 from sheet1? The output should go into cell AB on Sheet2.
Not to confuse the issue but the reason the code is done in this manner is so that data can be entered on sheet 1 which will be the active sheet on the screen at all times but data will be periodically be saved to sheet2.
Excel Statement i need to incorporate and output to Cell "AB" on sheet2:
=CONCATENATE(Sheet1!I9,", ",Sheet1!I10,", ",Sheet1!I11,", ",Sheet1!I12)
Current Code:
Option Explicit
Public dTime As Date
Sub ValueStore()
Dim dTime As Date
Dim ws1 As Worksheet
Dim ws2 As Worksheet
Set ws1 = ActiveWorkbook.Worksheets("Sheet1")
Set ws2 = ActiveWorkbook.Worksheets("Sheet2")
Dim lRow As Long
lRow = ws2.Range("A" & Rows.Count).End(xlUp).Row
With ws2
Range("X1:X" & lRow).Offset(1).Value = ws1.Range("F15").Value
Range("Y1:Y" & lRow).Offset(1).Value = ws1.Range("F14").Value
Range("Z1:Z" & lRow).Offset(1).Value = ws1.Range("F17").Value
Range("AA1:AA" & lRow).Offset(1).Value = ws1.Range("F16").Value
End With
StartTimer1
End Sub
Sub StartTimer1()
dTime = Now + TimeValue("00:00:05")
Application.OnTime dTime, "ValueStore", Schedule:=True
End Sub
Sub StopTimer1()
On Error Resume Next
Application.OnTime dTime, "ValueStore", Schedule:=False
End Sub

Try this:
Sub ValueStore()
Dim dTime As Date, rw As Range
Dim ws1 As Worksheet
Dim ws2 As Worksheet
Set ws1 = ActiveWorkbook.Worksheets("Sheet1")
Set ws2 = ActiveWorkbook.Worksheets("Sheet2")
'find the next empty row on ws2
Set rw = ws2.Cells(Rows.Count, "A").End(xlUp).Offset(1, 0).EntireRow
With rw
' note the .Range() here is *relative* to rw
.Range("A1").Value = Now '<< ensure a value is placed in colA....
.Range("X1").Value = ws1.Range("F15").Value
.Range("Y1").Value = ws1.Range("F14").Value
.Range("Z1").Value = ws1.Range("F17").Value
.Range("AA1").Value = ws1.Range("F16").Value
'method1 (contiguous vertical range)
.Range("AB1").Value = Join(Application.Transpose(ws1.Range("I9:I12").Value), ", ")
'method2 (join individual cells)
.Range("AB1").Value = Join(Array(ws1.Range("I9"), ws1.Range("I10"), _
ws1.Range("I11"), ws1.Range("I12")), ", ")
End With
StartTimer1
End Sub
