How to fix "? idparam not found in collection" in mysql insert stored proc

I am writing an insert query in mysql stored procedure .when i am trying to run i am getting error "?IDparam not found in collection" .I didnt give ID in insert as it should be autoincremented and i use it in update and delete later in this procedure.

This is Insert query from my proc: 
<pre>CREATE DEFINER=`root`@`%` PROCEDURE `insertproc`(
IN IDparam INT,
IN Pathparam VARCHAR(100),
IN fileNameparam VARCHAR(100),
IN Countparam VARCHAR(100),
IN CreatedBYparam DATETIME,
IN CreatedDateparam DATETIME,
IN Typeparam VARCHAR(100),
IN Statusparam VARCHAR(100),
IN crudparam VARCHAR(50))
BEGIN

IF(crudparam ='INSERT')
THEN
INSERT INTO pathmaster (
                        Path,
                        pathName,
                       fileName ,
                       Count,
                       CreatedBY,
                       CreatedDate,
                       Type,
                       Status
                        )
                        VALUES(
                             Pathparam,
                         (Select MAX(pathName) from pathmaster)+1,
                       FileNameparam,
                      Countparam,
                      CreatedBYparam,
                    CreatedDateparam,
                    Typeparam,
                    Statusparam
                );
END IF;

 MySqlParameter[] mysqlparam = new MySqlParameter[]
  {
     new MySqlParameter("Pathparam",Path.Trim()),

    new MySqlParameter("FileNameparam",filename.Trim()),
    new MySqlParameter("Countparam",count),
    new MySqlParameter("CreatedBYparam",date),
    new MySqlParameter("CreatedDateparam",date),
   new MySqlParameter("Typeparam",strType),
new MySqlParameter("Statusparam","pending"), 
    new MySqlParameter("ACTIONparam","INSERT")
   };
      ds = ExecuteProc("insertproc", mysqlparam);
