Cs1501: no overload for method 'createproduct' takes '9' arguments Solution

This error is very easy to understand. There are nine conflicts in the "createproduct" method without overloading. For example

Line 65: {Line 66: String categoryid = request. querystring ["categoryid"]; line 67: bool success = catalogaccess. createproduct (categoryid, newname. Text, Newdescription. Text, newprice. Text, newprice. Text, newimage1filename. Text, Newimage2filename. Text, newondepartmentpromotion. Checked. tostring (), Newoncatalogpromotion. Checked. tostring (); line 68: statuslabel. Text = Success? "Insert successful": "insert failed"; line 69: bindgrid ();

Obviously, I have a newprice. Text here, because I have defined only eight parameters in the ceateproduct method of catalogaccesss, and nine parameters are incorrect.
