    This is my code

    Sub Table1_SelectionChanged (ColName, Row)
    a = Row
    textbox1.Text = table1.Cell("Internal",a)
    textbox6.Text = table1.Cell("CldOd",a)
    textbox2.Text = table1.Cell("CldFrPos",a)
    textbox7.Text = table1.Cell("HtOd",a)
    textbox3.Text = table1.Cell("HtFPos",a)
    textbox8.Text = table1.Cell("AmtWire",a)
    textbox4.Text = table1.Cell("Pph",a)
    textbox9.Text = table1.Cell("WrSize",a)
    textbox5.Text = table1.Cell("CycTime",a)
    textbox10.Text = table1.Cell("Mach",a)
    Form2.Show
    form2.Refresh
    End Sub

    textbox10.text dumps an error code of object reference not set to an instance of an object.

    If I remark it out the sub works fine. :sign0148: :confused:

    I don't think that this is the problem here, but you should avoid showing a new form in the Table_SelectionChanged event. At the end of this event the focus returns to the table.
    Does TextBox10 exist?

    There is no Mach column in your CSV file.

    Thanks Erel

    I thought this text file worked under version 4 and was at a loss when it didn't with 5.50. I can see I have some learning to do. In the end I want to load it into a sqlite db, that will be a whole new can of worms. Thanks again for your fast response and you have created a nice product.
