Can view a form, can enter data, but won't post to database

I'm attempting to work on this form, at this time it is showing me my form, but it is not allowing me to enter the information into the database. Now as far as I can tell everything is correct, but I can't be sure. The only thing I can think that is out of place or wrong is that the code pointing to entering the data into the database once entered into the form is wrong.

I know I haven't sanitized my fields yet, so please don't tell me I need to. I am attempting to get this script written first, and I will do the clean up of the script after.

If someone can find the error, tell me what it is, and how to fix it, it be greatly appreciated.

Solution

Your query is missing a '

$query = "INSERT INTO ncmr ('ncmrsr', 'ncmrsc')  VALUES ('$ncmrsr', '$ncmrsc) WHERE id ='$id'";

Should be

$query = "INSERT INTO ncmr ('ncmrsr', 'ncmrsc')  VALUES ('$ncmrsr', '$ncmrsc') WHERE id ='$id'";

Notice the ' after $ncmrsc
