Hi John ,
You must give a value for x
so try for example (on the command window) :
>>FirstFct(5)
>>y
you should get y=25

How are you starting up your function? It appears that you might be using F5 or using Run from the menus. To run a function that takes input arguments, you need to go to the command line and enter the call there, giving the inputs on that line. For example,
FirstFct(12303)
