title: Ruby, sketchup-add another textbox to the unput box
body: <p>I am running this code through the ruby sketchup console.</p>
  
  <pre><code>            prompts = ["Stair Width", "Travel","Tread Thickness","Total Height","Riser Thickness","Stringer Width","Stringer Thickness","Top Hanger Thickness","Customer","Customer Address","Top Hanger Nose","Stair Nose","Flight"]
      defaults = [36.0,0.00,1.0,0.00,0.5,11.25,1.25,0.5,"My Builder", "234 Jimmys Street","Yes","Yes","Main"]
      list=["","","","","","","","","","", "Yes|No","Yes|No"]
  
      input = UI.inputbox prompts, defaults,list, "Stair Info"
          a,b,c,d,e,f,g,h,i,j,k,l,m=input
          cst=i.to_s
          adr=j.to_s
  ent = Sketchup.active_model.entities
      tr=(d/8.0).ceil
      rise=d/tr
      run=((b-(1+h))/(tr-1))
  </code></pre>
  
  <p>I would like to add an additional textbox beside the "Total Height" input box and make it equal tr when exiting the "Total Height" input box.
  Is there a way to add a textbox beside the Total Height input box and have it equal "tr" once leaving the Total Height input box?</p>
