Hi,

I am going out on a limb here. I have always used javascript for functions and while I am not sure if it will work in Formcalc, the following will work in Javascript:

if (this.rawValue == "1")

{

     values();

}

function values()

{

     xfa.host.messageBox("test");

} // end function

Hope that helps,

I do not believe that formCalc has support for functions.

Hello Paul / Nail ,

We have a Keyword for functions in Form calc like FUNC and ENDFUNC. So i feel we can use this but i am not sure about the syntax and i didt find any information in Help too.

Could you please search in your library wheather is there any Info or not.

Thank you for taking care,

Hi Rakesh,

If you look at page 966 of the XFA specification (http://partners.adobe.com/public/developer/xml/index_arch.html#xfa_28), then you will see how to decalre and call a function in FormCalc:

func MyFunction(param1) do param1*param1 endfunc // Declares a function

MyFunction(3) //Invokes the function, which returns 9

It looks like your previous FormCalc function was missing the "do" call.

Bear in mind that if you start putting functions in script objects, you will have to revert to Javascript.

Good luck,

Hi Rakesh,

It looks like in FormCalc you need to declare the function strictly before you call it. The attached example has both a Javascript function and a Formcalc function and while they both do the same thing (based on your original example) the Formcalc function is declared first.

Hope that helps,

Niall is right. The function must be declared before it can be used. A common practice is to put it on an Initialization event so it is available after that fires. The script object cannot be used as that is for Javascript only.
