Help with custom batch processing dialog

Where am I going wrong?

The "fd_btn" button has the function of locating a folder (It worked perfectly)

The "but_Run" button has the function import each file however I am getting this error on line 36, how can I fix this error ??? All help is appreciated. Thank you

You may want to reads Adobe Script Image Processor which is installed with Photoshop.  That script can do what you want to do. All you need do is record a one step action menu File>Scripts>YourScript.    Then use menu File>Scripts>Image Processor. Fill in the dialog check run action and select your action that runs your script.. The image processor can only save a jpg psd and Tiff

There a more powerful Plug-in script you can download and install Image Processor Pro.  Once install you access via men File>Automate>Image Processor Pro...

These script can also be run from Adobe Bridge and process files selected in bridge.

This script only imports from the folder.

File.prototype.fileExt = function () {
   return this.name.replace(/^.*\./, '');
};
var inputFolder = Folder.selectDialog("Please select the input folder");
if (inputFolder != null) {
    var fileList = inputFolder.getFiles();
   for (var a in fileList) {
   if (fileList instanceof File) {
   var fileExtension = fileList.fileExt();
   if (fileExtension === "png", "tif", "psd") {
    open(fileList);
} } }}

I'm a beginner I could not get it into the inside function but_Run.onClick = function ()

Let's see if anyone else after a light for you!
