Samantha Carisch and Taylor Sinclair had been forced to postpone their wedding twice because the mother-of-the-bride was battling MS.
Carisch said she can`t imagine getting married without her mother, but was fearful that time may be running out.
The couple was named one of five finalists in "The Knot Dream Wedding" competition and were hoping voters can help them get their big day back on track.
