Insert Row with Command Button Include Formulas and Merged Cells

[TileGal]

I am very new to VBA, and I understand coding. I need some help on a VBA code in Excel 2013.



A portion of my spreadsheet includes rows for quoting items. My end users are not very Excel savvy, so I have researched the code and cobbled together enough to create and use a button that will insert a row in the row number of their choice and include the formulas of the previous row (see below).

Where I'm getting stuck is keeping two sets of cells merged in the new row. Cells D(rowNum) through G(rowNum) should be merged, and H(rowNum) through J(rowNum). I've done lots of research on VBA code to insert a row and keep the merged cells, but I cannot figure out how to integrate it into my existing code. (This is where my lack of basic VBA rules knowledge comes in.)

I would really appreciate any help you can give, and if there's any additional information I need to provide, please let me know.

Thanks!!

Code:
Private Sub CommandButton1_Click()
Dim rowNum As Integer
On Error Resume Next
rowNum = Application.InputBox(Prompt:="Enter Row Number where you want to add a row:", _
Title:="Insert Quote Row", Type:=1)
Rows(rowNum & ":" & rowNum).Insert Shift:=xlDown

Rows(rowNum + 1).Copy

Rows(rowNum).PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone, _
SkipBlanks:=False, Transpose:=False
Application.CutCopyMode = False


End Sub
