Unless you are told this is the relationship you may want to re-consider the relationship here. When you extend a class it should make sense to say

manufacturer is a television

Does that make sense to you? It doesn't to me. This is called an is-a relationship. A has-a relationship would make more sense to me

a television has a manufacturer

You would then make one of televisions instance variables be a manufacturer.

As far as the error messages go, you are calling super and passing it those arguments. It is going to look for a constructor in the super class that takes those 3 constructors. Did you supply a constructor like that?

For the second error. You are calling a method, it should have () at the end.

super.getInventoryValue()

not 

super.getInventoryValue

[Raven9]

I got those 2 error corrected, now have the following error:

C:\Documents and Settings\AdminUser\My Documents\InventoryPart3.java:92: invalid method declaration; return type required
public Television(int ItemNumber, String ProductName, int UnitsStock, double UnitPrice, String mfgName) {

Show the changed code please. Remember, constructors take the same name as the class.

This is the original error which you claim was fixed. You are still trying to call a constructor that does not exist. The order, type and number of parameters must match.

[Raven9]

I made corrections to the other errors, then this one came back. I am not sure exactly how to fix this problem. This is all new to me and trying to grasp this the best I can.

[Junky]

It is easy to fix. Just like you have been told numerous times you have tio make sure the parameters match: order, type, number

public void methodOne(String s, int i) { }

public void methodTwo(int x) {}

public void methodThree(String a, String b, String c) { }

public void doStuff() {
    methodOne(7, "hello"); // error order is wrong

    methodTwo("hello"); // error type is wrong

    methodThree("hello", "world"); // error number is wrong
}
