You've initialised a JSpinner like this: java numberOfBoxesJSpinner = new JSpinner(new SpinnerNumberModel(0, 0, 5,1)); When you want the value of that one, just use the line: java numberOfBoxesJSpinner.getValue();

For whatever reason, java won't let me do an easy type cast. So I parsed the integer from the object and performed the calculations. JSpinner.getValue(), Earlier in the thread, we tried C style casting, but apparently that is illegal if an Object is getting returned. It should return an Integer (at least I think that), but it doesn't. I think its an acceptable workaround for the time being. edited for typos This post has been edited by KYA: 30 Nov, 2008 - 11:29 AM
