Perhaps I need a refresher on the use of subforms...

I would like to be able to use a command button to direct the user to a new
form to enter additional information to keep the main form (screen) as clean
as possible.

I have placed the button and am able to get it to open a new user form,
however, I don't know how to get that data to be placed into the database
like it does on the original form. And maybe there is another way to go about
this? (Multipage?..then how do I hide that multipage on the original form?)

ORIGINAL FORM CODE
Private Sub cmdAddPrj_Click()
Dim iRow As Long
Dim ws As Worksheet
Set ws = Worksheets("ProjectData")

'find first empty row in database
iRow = ws.Cells(Rows.Count, 1) _
.End(xlUp).Offset(1, 0).Row

'check for a project number
If Trim(Me.txtPrjNo.Value) = "" Then
Me.txtPrjNo.SetFocus
MsgBox "Please enter a project number"
Exit Sub
End If

'copy the data to the database
ws.Cells(iRow, 1).Value = Me.txtPrjNo.Value
ws.Cells(iRow, 2).Value = Me.txtPrjNm.Value
ws.Cells(iRow, 9).Value = Me.txtPrjTyp.Value
ws.Cells(iRow, 10).Value = Me.txtCon.Value
ws.Cells(iRow, 11).Value = Me.txtEst.Value
ws.Cells(iRow, 12).Value = Me.txtPm.Value
ws.Cells(iRow, 21).Value = Me.txtJobcst.Value
ws.Cells(iRow, 22).Value = Me.txtHrdCst.Value
ws.Cells(iRow, 23).Value = Me.txtMrkup.Value
ws.Cells(iRow, 24).Value = Me.txtGm.Value
ws.Cells(iRow, 25).Value = Me.txtSfEa.Value
ws.Cells(iRow, 26).Value = Me.txtPrjCstSfEa.Value
ws.Cells(iRow, 27).Value = Me.txtHcSfEa.Value
ws.Cells(iRow, 28).Value = Me.txtMuSfEa.Value
ws.Cells(iRow, 4).Value = Me.txtPrjStrAddr.Value

'clear the data
