ListBox column count VBA Excel

I just spent two hours going over your very badly named code. It took me that long just to figure out why you need so many columns.
Private Sub CommandButton1_Click() With UserForm1 .TextBox1.Text = ListBox1.List(ListBox1.ListIndex) .TextBox2.Text = ListBox1.List(ListBox1.ListIndex, 1) .TextBox3.Text = ListBox1.List(ListBox1.ListIndex, 2) .TextBox4.Text = ListBox1.List(ListBox1.ListIndex, 3) .TextBox5.Text = ListBox1.List(ListBox1.ListIndex, 4) .TextBox6.Text = ListBox1.List(ListBox1.ListIndex, 5) End With End Sub
Since you are only using TestBox1" as a display for the User to select from:
In "ListBox 1" keep one column, separate the itmes (in one string) with " | " . Keep all the items in all the Rows in an array. In cbtUpDate_Click
Private Sub CommandButton1_Click() Dim RowNum ArrIndex = Me.tbxRecords.ListIndex - 1 With Me .tbxRecordRing1.Text = arrRecords(arrindex, 0) .TtbxRecordHole1.Text =arrRecords(arrindex, 1) .tbxRecordDepth.Text =arrRecords(arrindex, 2) .tbxRecordChangeCode14.Text = arrRecords(arrindex, 3) .tbxRecordChangeCode2.Text = arrRecords(arrindex, 4) .tbxRecordDescription1.Text = arrRecords(arrindex, 5) End With ' The names are out of order, but that is the way to name controls! 'If you want really well structured code. Create an Enum in modGlobals for all twelve of the items. End Sub
Enum ItemArrayIndexNumber ndxRecordLocation1 = 0 ndxRecordRing1 ndxRecordHole1 ndxRecordDepth2 ndxProductionCodes1 ndxProductionDetail1 ndxRecordChangeCode1 ndxRecordChangeCode2 ndxRecordDescription1 ndxRecordChangeCode1RT ndxRecordChangeCode2RT ndxRecordChangeCode2RT End Enum ' I know, the names are out of order
This changes the sample code above to read like
.tbxRecordRing1.Text = arrRecords(arrindex, .ndxRecordRing1)
Note how this makes your code "Self Correcting".

"Look, I'm working on Recording Ring one. Yep, the index is Recording Ring one. OK!"

My finale bits of programming practices advice. name a Module holding you Global Variables "modGlobals," and prefix Class Module names with "cls" or "obj."

Public GlobalData(6000) As objRowReference 'Instantiated in UserForm1 Private Sub cmdAdd_Click() 'Used in: 'UserForm1 Private Sub btnSave_Click() 'UserForm1 Private Sub btnNew_Click() 'UserForm1 Private Sub ListBox3_DblClick
This is atrocious Naming system, most especially when you don't even have 27 textbox controls.
