Hi psingh: sorry that no one has answered your query before now. If you check this link:
http://www.cic.gc.ca/english/immigrate/skilled/complete-applications.asp you will notice that your occupation does not appear in the most up to date list of 29 occupations (NOC 29). Unless you have worked for at least one full year in one of those 29 occupations in the past 10 years, OR have an approved job offer in a skilled category (level 0, A, or B) you will not qualify to apply under the Federal Skilled Worker programme. I wonder if you might have been looking at an OLD list of occupations in which NOC 3212 was included and has now been removed, hence the line through. I hope this answers your question. Good Luck.
