Multiple Selector (“selector1, selector2, selectorN”) error

[niceguyblue]

$("#form-part4,#form-part5,#form-part6,#form-part7,#form-part8,#form-part9,#form-part10,#form-part11,#form-part12").submit(function(){ alert(this.id) });

here each id is a individual form but for #form-part10,#form-part11,#form-part12 is taking them together.

That's because you forgot to close the form for form-part10 after the table - it continues on and encompasses the other forms as well.
