Delete blank rows on range except last row - excel

Question

I have this code where i can search for the first two blank cells and place an "x" on the first cell that contains the blank. For testing purposes i have separated the the code into two command buttons. For First command button searches the blank cells and places the "x" and second command button finds the "x" and deletes the row and all other rows after it.
My problem is, i want it to delete all rows after the "x" but to leave the last row which contains the overall Total.
Here is my code from the two command buttons :
Sub findEmptyCells()
Dim lastRow As Long, i As Long
Dim firstEmptyCell As Range
lastRow = Cells(Rows.Count, 12).End(xlUp).Row
For i = 12 To lastRow
If Cells(i, 12).Value = "" And Cells(i + 1, 12).Value = "" Then
Set firstEmptyCell = Cells(i, 12)
Exit For
End If
Next i
MsgBox ("There are no two empty cells in a row")
Exit Sub
End If
firstEmptyCell.Value = "x"
End Sub

Dim srchRng As Range
Set srchRng = Range("L7:L500")
Dim c As Range
For Each c In srchRng
If c.Value = "x" Then
Range(c, Range("L500")).EntireRow.Delete
Exit For
End If
Next
End Sub

Delete Rows Identified By Merged Cells
Option Explicit
Sub DeleteRows()
Const Col As String = "L"
Const fRow As Long = 13
Const mcCount As Long = 5
Dim ws As Worksheet: Set ws = ActiveSheet ' improve!
Dim lRow As Long: lRow = ws.Cells(ws.Rows.Count, Col).End(xlUp).Row
Dim cCell As Range
Dim r As Long
For r = fRow To lRow - mcCount
'Debug.Print r
Set cCell = ws.Cells(r, Col)
If cCell.MergeArea.Cells.Count = mcCount Then
If Len(CStr(cCell.Value)) = 0 Then
cCell.Offset(-1).Resize(lRow - r + 1).EntireRow.Delete
Exit For
End If
r = r + mcCount - 1
End If
Next r
MsgBox "Rows deleted.", vbInformation
End Sub
