In the earlier message, you had these lines of code:

Private Source As Range
Private Index As Long

In this line:
For Index = 1 To Source.Rows.Count
index is just a counter so you can loop through the rows in source.

Sometimes (always???), it's easier to break the code into little pieces and see
what happens in those smaller pieces.

Try this in a test workbook:

Option Explicit
Sub testme()

Dim mySource As Range
Dim myIndex As Long

Set mySource = ActiveSheet.Range("c3:d9")

For myIndex = 1 To mySource.Rows.Count
MsgBox myIndex & vbLf & mySource.Rows(myIndex).Address
Next myIndex

End Sub

I used different variable names. Both Source and Index are terms that VBA
owns. And even though it won't confuse excel/vba, it may confuse me.

ps. Try this version, too:

Option Explicit
Sub testme()

Dim mySource As Range
Dim myIndex As Long

Set mySource = ActiveSheet.Range("c3:d4, g9:L11")

For myIndex = 1 To mySource.Rows.Count
MsgBox myIndex & vbLf & mySource.Rows(myIndex).Address
Next myIndex
End Sub

Just to show you how mysource.rows.count only looks at the first area in that
range.

HI Mr. Peterson, Thank you so much for your quick response! It was very
helpful in removing my .Clear error. I decided to remove the row source from
the list box to solve the problem.
If it is not too much trouble, I was wondering if you could explain the
reference in the coding below:

Private Sub LoadAnimals()
Dim animal As New Scripting.Dictionary
For Index = 1 To Source.Rows.Count 'WHAT DOES THIS INDEX REFER TO?
animals = Source.Cells(Index, "B").Value 'animal type from table column 2
If Not animal.Exists(animals) Then
animal.Add animals, animals
Type_cmb.AddItem animals
End If
Next
End Sub

'code pulled from a portion of the LoadData:
With lstData
.Clear
animals = Me.Type_cmb.Value
For Index = 1 To Source.Rows.Count 'WHAT DOES THIS INDEX REFER TO?
If animals = Source.Cells(Index, 2) Then
.AddItem Source.Cells(Index, 1) '

Thank you again! This is like piecing together a puzzle, and my supervisors
have no clue how to do this either!

Sincerely,
Kristina

First, this:

If Not IsNumeric(Me.Animal_ID_tb.Text) Then Exit Sub ' what does this mean?

Says that if that field (the Animal ID textbox???) doesn't look like a number,
then the update procedure should stop.

Second, I bet you're populating that listbox (lstData) with a rowsource--either
via the properties window or through some code you didn't share.

You could either stop doing that or use code like:

LstData.RowSource = ""
LstData.Clear

This will remove all the items from the listbox--is that what you wanted?

Hello there,

I am trying to creat an Update/Delete form for a livestock inventory
