in reply to Updating the same line Text Widget

According to Tk::Text (section "Indices") you might have meant 'startline.end' instead of 'end startline'

    When using 'startline.end' there is a Tk Error that the index is bad

      Then maybe 'startline' is nothing legal. I only found 'linestart' in the docu. 'end linestart' could actually work to mean the start of the last line in a text, if I read the documentation correctly

      If not, try something like '1.0' or 'x.0' with x the line number of the line where your filesize is put in the text widget
