javascript doesnt work after using the "save as other" menu

[AdsaAntonio]

i have a pdf file with javascript, the code works perfectly as long i´m working in the file, but when i use the "save as other/reader extended pdf/enable more tools" and i open the new file, the code no works at all.

i use the javascript console and i got this message:

ReferenceError: showCharCount is not defined

1:Field:Keystroke

i´m using this code to get the character count of a field:

in the fields from which I need to take the count, in the custom keystroke script:

showCharCount();

in a second, thirtd and fourt field (this fields are not visible to the end user, it is only for the following function):

// Document level function 

function showCharCount() { 

    // gets whats on the field 

    var num = AFMergeChange(event).length; 

    // show characters 

    getField("count").value = num; 

}

and finally in the "totalcount field":

// Set the minimum number of characters 

    var min = 1900;

event.value = ( this.getField("count").value + this.getField("count2").value ) + this.getField("count3").value + this.getField("count4").value;

// Set the value of the other text field to show how many character have been entered 

    getField("totalcount").value = event.value + " of " + min;

i got no background in programming so i really don´t know what i´m doing wrong.

P.S.

sorry, my english is not so good

Where did you place the showCharCount function, exactly?

[AdsaAntonio]

i put the function in the custom keystroke script in the properties section on the field from which i need to get de count

[try67]

You only placed the call to the function there. Where's the actual function definition itself?

[AdsaAntonio]

i put three diferent field to get the count of each field i need, this fields are not visible for the end user i just use it to get de count of each field and finally get the sum of this fields for display it on a totalcount field

this is and example of mi pdf file

Define the function at document level.

[AdsaAntonio]

where can i do that?

sorry for my kind of question but a have no background in programming, this is my first try

Tools - JavaScript - Document JavaScripts... Do not use the Edit All JavaScripts command for that.
