unit consolidation, page-4

Hi,
I'm a bit of a newby to stock trading and am a little confused on what this consolidation means. What i am particularly concerned about is witnessing the stock price fall to 0.00 ! Does this mean that i had to sell before this happened? Will the stock price pick up from what it was on the 15th? Do I have to transfer my shares to asx:CQODA ?

Apologies for all the Q's but i seem to not understand what consolidation means.

Thanks
