Turn a case statement into a function

Question

I have a case statement (from an earlier post - thank you) that works. I was wondering if it could be edited and change into a function instead. I think it would be cleaner. The variable is set in the Form Properties (pCounterA).
switch (pCounterA.value)
    case "1":
    profileA__1image.rawValue = profileA_1image.value.image.value;
    pCounterA.value = "2";
    break;
    case "2":
    profileA__1image.rawValue = profileA_2image.value.image.value;
    pCounterA.value = "3";
    break;
    case "3":
    profileA__1image.rawValue = profileA_3image.value.image.value;
    pCounterA.value = "4";
    break;
    case "4":
    profileA__1image.rawValue = profileA_4image.value.image.value;
    pCounterA.value = "5";
    break;
    case "5":
    profileA__1image.rawValue = profileA_5image.value.image.value;
    pCounterA.value = "1"; // loops back to the first image
    break;

Hi,
If you insert a script object by right clicking on the root container (often "form1"). It will appear unnamed in the root / variables in the hierarchy.
First of all you should name the script object, staying away from reserved names, eg "this". Say "myScripts"
Script objects can only contain Javascript, so you would need to convert FormCalc scripts (not an issue in your case).
When you go into the script object, you start off a function with "function" followed by its name and inputs in brackets. The extent of the function is given by curly brackets:
function changeImage(vCounter)
     switch (vCounter)
         case "1":
         profileA__1image.rawValue = profileA_1image.value.image.value;
         pCounterA.value = "2";
         break;
     } // close switch statement
} // close function
Back in the form you can call the function by referencing the name of the script object and the name of the function.
myScripts.changeImage(pCounterA.value);
A couple of things to note:
The input in the script can refer to an objects value or a global variable, but in the function you can assign it s different name. So above the input pCounterA.value is EQUAL to vCounter in the function;
You can have several inputs in the call for the function separated by commas;
Don't have the same name for the script object AND the function
Hope that helps,
