This error means you have a query with several columns named and a different number of values specified in the query. For example, the following query would give that error because three columns are listed but four values are given:
insert into table (name,address,phone) values ("Mike","Main Street","2222222222","Hello");
That's it!!
Just check the number of fields you have listed (count) and compare that with the number of values and you'll see the problem.
