Phrag. Eric Young - flower spike showing signs of shriveling. Help!

[AndreaK]

I need help answering the question, "Why is it shriveling again?". This orchid has tried to bloom for several years in my care, four to be exact. The first two years I thought I understood what went wrong, inadequate watering due to our going on vacation. The following year I am certain of the cause of the demise of the flower spike: kids + rough housing = orchid hit the floor! This year I have been diligent about keeping it moist. As you can see in the pictures the stem has started to wrinkle yet again. The first two years it proceeded to dry out and die off. So far it has not progressed beyond the wrinkling at the time of the picture. I am desperately wanting to see this plant bloom. Any suggestions will be well received.
