Different sheet pasting - vba

Question

I have written a code which gives me the errors (if any cell is non numeric) in a separate sheet called "Error_sheet".
But the output is a bit clumsy as it gives me non numeric cell address in a confusing fashion. Like the errors will not be pasted one after another. There will be some blanks in between if there are more than one non Numeric cells.
Sub Test()
Dim LastRow As Long, i As Long
LastRow = Cells(Rows.Count, "A").End(xlUp).Row
For i = 2 To LastRow
If IsNumeric(Range("A" & i).Value) Then
Else
Sheets("Error").Range("A" & Row).Value = "Error in" & i & " row of ColumnNAme"
Row = Row + 1
End If
Next i
End Sub
It gives me output like shown below but can I get the output like Error in 7,14 rows of column name in a desired cell of "Error_sheet".

Answer 1

My understanding of what you've written is that you want something like this.
Option Explicit
Sub Test()
' Unqualified book/sheet below, means code will always run the isnumeric check on the cells of the active sheet. Is that what you want? '
Dim LastRow As Long
LastRow = Cells(Rows.Count, "A").End(xlUp).Row
Dim Index as long
Dim i As Long
Dim NonNumericRows() as string
Redim NonNumericRows(1 to lastrow)
For i = 2 To LastRow
If not(IsNumeric(Range("A" & i).Value)) Then
Index = index + 1
NonNumericRows(Index) = cstr(i)
End if
Next i
Redim preserve NonNumericRows(1 to index)
Sheets("Error").Range("A1").Value = "Error in row(s): " & strings.join(nonnumericrows,", ") & " of ColumnNAme"
End Sub
Hope it works or helps.

Like QHarr suggested, using Option Explicit is normally a good idea, and try not to use VBA operators as variables.
Also when working with more than 1 sheet, its best to define each in the code. I dont know what your first sheet is called, so please change the line: Set shSource = Sheets("Sheet1") to suit:
Option Explicit
Sub SubErrorSheet()
Dim lr As Long, i As Long
Dim shSource As Worksheet, shError As Worksheet
Set shSource = Sheets("Sheet1")
Set shError = Sheets("Error")
lr = shSource.Range("A" & Rows.count).End(xlUp).Row
For i = 2 To lr
If Not IsNumeric(shSource.Range("A" & i).Value) Then
shError.Range("A" & Rows.count).End(xlUp).Offset(1, 0).Value = "Error in row " & i & " of ColumnNAme"
End If
Next i
End Sub
