display only cells with value in Pop Up Form - excel

Question

the macro below takes two cell values (from first and second column)
and displays the column and there cell content in a Pop up Form
Im trying to add the condition that only the column and cell value is displayed if the cell contains value.
something like that =IF(A1<>"",result,"")
but I dont know how to implement that for all cells not only for a specific one.
Option Explicit
Const rangeForSearch = "G2"
Const rowTitles = 4
Dim arrTmp
Dim lastRow As Long, lastColumn As Long
Dim textForSearch As String, textForSearch_withoutSpaces As String
Dim strTmp As String
Dim i As Long, j As Long
Sub searchPerson()
Application.ScreenUpdating = False
With ActiveSheet
textForSearch = .Range(rangeForSearch)
If textForSearch = "" Then
MsgBox "Input text in cell """ & rangeForSearch & """ and try again!", vbCritical
Application.ScreenUpdating = True
Exit Sub
End If
lastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
lastColumn = .Cells(rowTitles, .Columns.Count).End(xlToLeft).Column
If lastRow <= rowTitles Or lastColumn <= 2 Then
MsgBox "Dataset is wrong! Check it and try again!", vbCritical
Application.ScreenUpdating = True
Exit Sub
End If
arrTmp = .Range(.Cells(rowTitles, "A"), .Cells(lastRow, lastColumn))
End With
'---------------------------------------
textForSearch_withoutSpaces = Replace(textForSearch, " ", "")
For i = LBound(arrTmp, 1) + 1 To UBound(arrTmp, 1)
strTmp = Replace(arrTmp(i, 1) & arrTmp(i, 2), " ", "")
If StrComp(textForSearch_withoutSpaces, strTmp, vbTextCompare) = 0 Then Exit For
Next i
If i = UBound(arrTmp, 1) + 1 Then
strTmp = textForSearch & vbCrLf & vbCrLf & "No dataset!"
Else
strTmp = textForSearch
For j = 3 To lastColumn
strTmp = strTmp & vbCrLf & vbCrLf & arrTmp(1, j) & ": " & arrTmp(i, j)
Next j
End If
Application.ScreenUpdating = True
MsgBox strTmp, , "Result"
End Sub

Answer 1

maybe
For j = 3 To lastColumn
If Not IsEmpty(arrTmp(i, j)) Then strTmp = strTmp & vbCrLf & vbCrLf & arrTmp(1, j) & ": " & arrTmp(i, j)
Next j
