Updating control value of HTML Textbox in VBA

I have an excel with over 100 HTML textboxes that need their control values to be updated to match cell references. I am getting a runtime error 1004, Application or object defined error.

I have tried all combinations of the below to no avail.

• Test 1 from https://www.ozgrid.com/forum/index.php?thread/71462-copy-text-from-html-text-box/

• Tests 2 and 3 from https://www.pcreview.co.uk/threads/addressing-htmltext-object-in-spreadsheet-vba-script.4014065/

  Sub test()
  
  
  'test1
          Dim TB As OLEObject
      'test2
          'Dim TB As TextBox
      'test3
          'Dim TB As msforms.TextBox
  
      Set TB = ActiveSheet.TextBoxes(HTMLText99)
      'Set TB = ActiveSheet.OLEObjects(HTMLText99)
  
      TB.Value = ActiveSheet.Cells(5, 7)
      'TB.Text = ActiveSheet.Cells(5, 7)
      'TB.Object.Value = ActiveSheet.Cells(5, 7)
      'TB.Object.Text = ActiveSheet.Cells(5, 7)
  End Sub
  

Interestingly, if i just do a simple code (see below), the visible value of the HTML box changes as expected, but once I click "Detail view" in the developer tab, the visible value reverts back to the control value which I can see when I open properties on the HTML textbox.

ActiveSheet.HTMLText99.Value = ActiveSheet.Cells(5, 7)
