Thank you Jason!!
Now here is my question: this code (with the blank spaces) is generated by Form Builder so I am now wondering whether there is a fix/patch for your extension to prevent blank spaces from being inserted in the first place? What confused me is that the form works perfectly fine if I don't use checkbox groups.
Can you make a recommendations to help avoid this glitch? I vaguely recall I was asked to replace a "WAFB_ListValues.htm" file but that was for DW CS4 so I was not sure if it applies to CS5 as well.
Your support is outstanding - I have never come across any company responding as quickly as you do so THANK YOU!!!!! :o)
