Can you help me solve these challenges in the search code in the list box?

[saftawy1]

This code works fine in the listbox, But when you try two scenarios, the following happens:
1) when replacing a line (myCols = Array(1, 3,4, 5, 7, 10) with TextBox and let TextBox 2 written inside it (1,3,4,5,7,10) it gives me an error message (application defined or object defined error
It is marked on the next line in the code ( a(ii + 1, j) = ws.Cells(i, myCols(ii)).Value) . What is the solution to this challenge?

2) when replacing a line (myCols = Array(1, 3,4, 5, 7, 10) with Textboxes containing separate column numbers are written as follows (myCols = Array( TextBox,3TextBox4, TextBox5,TextBox6 ,TextBox7, TextBox8) It works fine, but if one of the textboxes is empty, it gives me the following error message type mismatch
It is marked on the next line in the code ( a(ii + 1, j) = ws.Cells(i, myCols(ii)).Value) . What is the solution to this challenge?

    Dim X, ws As Worksheet, i As Long, j As Long, lastRow As Long, y As Long
    With Me.ListBox1
        .Clear
        .ColumnCount = 6
        .ColumnWidths = ""
        Set ws = ThisWorkbook.Sheets("data")
        X = Application.Match(ComboBox1.Value, ws.Rows(1), 0)
        If Not IsError(X) Then
            lastRow = ws.Cells(Rows.Count, "e").End(xlUp).Row
                        Dim a, myCols, ii As Long
            ReDim a(1 To 6, 1 To lastRow)
            myCols = Array(1, 3, 4, 5, 7, 10)
            For i = 1 To lastRow
                If TextBox1 <> "" And InStr(ws.Cells(i, X), TextBox1) <> 0 Then
                    j = j + 1
                    For ii = 0 To UBound(myCols)
                        a(ii + 1, j) = ws.Cells(i, myCols(ii)).Value
                    Next

                End If
            Next i
            '.......................................................
                        For i = 1 To lastRow
                If TextBox1 = "" Then
                    j = j + 1
                    For ii = 0 To UBound(myCols)
                        a(ii + 1, j) = ws.Cells(i, myCols(ii)).Value
                    Next

                End If
            Next i
            '............................................................

            ReDim Preserve a(1 To UBound(a, 1), 1 To j)
            .Column = a
        End If
        End With

Scenario 1:

myCols = Split(TextBox2, ",")

Scenario 2:

Dim s As String
s = TextBox3 & "," & TextBox4 & "," & TextBox5 & "," & TextBox6 & "," & TextBox7 & "," & TextBox8
Do While InStr(1, s, ",,") > 0
    s = Replace(s, ",,", ",")
Loop
myCols = Split(s, ",")

in two scenarios :
it gives me an error message (application defined or object defined error
It is marked on the next line in the code ( a(ii + 1, j) = ws.Cells(i, myCols(ii)).Value)
