Your code will only work if text6, text9 and textadditamt1 are all on
the same band.  Your code also implies that codeblocks provide the
values to the text properties of text6 and textadditammt1.

If this is correct then the blank values are probably caused by a null
value in a field.  Try the following. (It's untested so your mileage may

   function TEXT9_canRender()
      this.text = 0
      if not empty(this.parent.text6.text())
         this.text += this.parent.text6.text()
      if not empty(this.parent.textadditamt1.text())
         this.text += this.parent.textadditamt1.text()

If text6, text9 and textadditamt1 are not all on the same band please
give details of where each one is placed and exactly how the text value
for each text object is derived.
