Can anybody tell me why its happening ?
As already pointed out by others, it would appear you've typoed the name of the column in your SQL or the column doesn't exist at all.
Going further with that the first thing you should consider doing at this point is logging in using the mysql client and attempting to run the SQL code you are scripting from there. Run an "explain" on the table should give you some idea what the valid column names are.
