Can't write code to find last data row in excel user form

Please forgive me, but I'm on a very steep learning curve. I'm not sure where to put this code. I already have code for the "UserForm_Initialize()" event as shown here

Private Sub UserForm_Initialize()

	LastRow = FindLastRow
	GetData

	End Sub

Do I need to delete this code and replace it with the code you suggested (and include the line "GetData")?

Also, I am guessing I should delete the existing code for finding the last row.

Private Function FindLastRow()

Dim r As Long

r = 2
Do While r < 65536 And Len(Cells(r, 1).Text) > 0
    r = r + 1
    
Loop

FindLastRow = r

End Function

Thanks for your patience. Rome wasn't built in a day"
