Export tooltips to a file

I'm trying to use Thom Parker's Javascript suggestion to export tooltips to a file and append the list to a PDF.

Here's the script from:

https://answers.acrobatusers.com/How-to-export-tooltips-to-a-text-file-or-other-document-q86962.aspx

var cSummary

for(i=0;i<this.numFields;i++)

{

   var cName = this.getNthFieldName(i);

   var cToolTip = this.getField(cName).userName;

   cSummary += cName + " : " + cToolTip + "\n";

}

this.createDataObject(this.documentFileName.replace(/\.pdf/,"_Tooltips.txt",cSummary);

If I run this in the Javascript console of Acrobat XI on a Mac I get:

SyntaxError: missing ) after argument list

1:Console:Exec

undefined

Can someone help me to debug this?

Thanks!
