It is saying that ..serial does not exist...is that true ?

Please avoid sending emails to the personal email addresses but use the community mailing lists for that.

For the error you mentioned please follow the steps I mentioned in my last email as you are doing it the wrong way. 

Create a sequence first and then you can assign that sequence to this column. You can not assign SERIAL like this, it has to be a sequence name in there.
