VBA EXCEL- Comparing listbox item to cell value (string)

Question

My list box is on a form. When a user selected list items they are stored in a column. Later when m edit button is clicked I would like to read in these values and add them onto a selected list (Listbox_selectedCategories) on the form and remove them from the other list box (Listbox_categories) The error that the VBA editor is throwing is error 381 could not get list property. Invalid property array index. I have checked both the value of x and index in the immediate window which are iterating as expected.I have also tried this without the Cstr function,same error. The compiler is highlighting the if statement as the point of error. Im sure this is some fundamental misunderstanding I would appreciate any help or direction. Thanks.

 Public Sub dataLoad()
 Dim x As Integer
 x = 0

NewQueryForm.targetingDescription.value = ActiveCell.Offset(1, 0).value
NewQueryForm.booleanDescription.value = ActiveCell.Offset(1, 1).value
NewQueryForm.startDate.value = ActiveCell.Offset(1, 3).value
NewQueryForm.endDate.value = ActiveCell.Offset(1, 4).value
NewQueryForm.dfpCount.value = ActiveCell.Offset(1, 5).value

NewQueryForm.Text_300Rates = ActiveCell.Offset(1, 8).value

NewQueryForm.Text_160Rates = ActiveCell.Offset(2, 8).value

NewQueryForm.Text_728Rates = ActiveCell.Offset(3, 8).value

NewQueryForm.Text_PollRates = ActiveCell.Offset(4, 8).value

NewQueryForm.Text_CMRates = ActiveCell.Offset(5, 8).value

NewQueryForm.Text_ExCMRates = ActiveCell.Offset(6, 8).value



Call NewQueryForm_Initialize

Sheets("CAT").Activate
Range("A1").Activate
ActiveCell.Offset(0, loopCount).Activate

While ActiveCell.Offset(1, 0).value <> ""
x = x + 1
Dim index As Integer

'Adding and removing items from list
NewQueryForm.ListBox_selectedCategories.AddItem ActiveCell.Offset(x - 1, 0).value

For index = 0 To NewQueryForm.ListBox_categories.ListCount - 1

If CStr(NewQueryForm.ListBox_categories.List(index)) = ActiveCell.Offset(x - 1, 0).value Then
            NewQueryForm.ListBox_categories.RemoveItem (index)
        End If

Next index

'Adding and Subtracting from global percent label variables
selectedCategoryLabel = selectedCategoryLabel + categoryPercent(ActiveCell.Offset(x - 1, 0).value)
categoryLabel = categoryLabel - categoryPercent(ActiveCell.Offset(x - 1, 0).value)

'Setting next cell down active
ActiveCell.Offset(1, 0).Activate
Wend

'updating labels
 NewQueryForm.selectedPercent.Caption = CStr(Round(selectedCategoryLabel, 2)) & "%"
 NewQueryForm.categoryPercent = CStr(Round(categoryLabel, 2)) & "%"





NewQueryForm.Show
End Sub

Following is the code I tried. I got the exact same error. And here is how I solved it.

BINGO: EXIT THE LOOP :)

Option Explicit    
'--show form on Sheet with Reg Edit mode
 Private Sub CommandButton1_Click()
    UserForm1.Show vbModeless
 End Sub   

'--Form codes within Form

Option Explicit

Private Sub cmdAddRange_Click()
Dim ws As Worksheet
Dim rng As range
Dim inputArray As Variant
Dim lRow As Long
Dim index As Integer

Set ws = Sheets(1)
Set rng = ws.range("B2")
lRow = ws.range("B" & ws.Rows.Count).End(xlUp).Row
inputArray = Application.WorksheetFunction.Transpose(rng.Resize(lRow).Value)

'Adding item to List one by one from Array
'For index = LBound(inputArray) To UBound(inputArray)
'UserForm1.ListBox1.AddItem inputArray(i)
'Next i

'Adding items to List box at ones from Array
UserForm1.ListBox1.List = inputArray
UserForm1.ListBox2.List = inputArray

End Sub

Private Sub cmdRemoveRange_Click()
Dim ws As Worksheet
Dim index As Integer

    Set ws = Sheets(1)

    '-- Remove  from listbox1
    For index = 0 To UserForm1.ListBox1.ListCount - 1

        If Not IsEmpty(ActiveCell.Value) Then
            If UserForm1.ListBox1.List(index) = ActiveCell.Value Then
                UserForm1.ListBox1.RemoveItem (index)
                MsgBox ActiveCell.Value & " deleted. And Golden Line *Exit For*"
                Exit For '-- golden line
            End If
        End If
    Next index

End Sub

Here is the Form I tried out:
