submit form data programmatically android (data lost)

I am making an app for myself to see when classes to my university (that are full) become available.

I need my app to be able to programmatically enter information into a 'class search' form and press the submit button so that I can check if any classes show up that are open.

Here is the website of the form: https://css.nevada.unr.edu/psc/rncssprd/EMPLOYEE/HRMS/c/COMMUNITY_ACCESS.CLASS_SEARCH.GBL

So far I can enter in the data to the form and see it displayed in a webview. The problem is that when I have the program click the submit button nothing happens. Well, actually it does search however the previous data that I submitted gets lost and it searches with no values in the form.

This is my code so far:

public class Main extends Activity{

String URL = "https://css.nevada.unr.edu/psc/rncssprd/EMPLOYEE/HRMS/c/COMMUNITY_ACCESS.CLASS_SEARCH.GBL";
WebView mWebview;

int noRepeat = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    new FetchItemsTask().execute();

}

private class FetchItemsTask extends AsyncTask<Void,Void,Boolean> {

    @Override 
    protected void onPreExecute() { 

    }

    @Override
    protected Boolean doInBackground(Void... params) {
        // TODO Auto-generated method stub

        return true;
    }

    @Override
    protected void onPostExecute(Boolean result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);


            mWebview = (WebView ) findViewById(R.id.webView1); 
            // load login url
            mWebview.loadUrl(URL); 
            //mWebview.setVisibility(View.INVISIBLE); 
            mWebview.getSettings().setJavaScriptEnabled(true); 

            mWebview.setWebViewClient(new WebViewClient() { 

                 public void onPageFinished(WebView view, String url) { 

                        // first time go to search page 

                         Toast.makeText(getApplicationContext(), "done loading login, pressing button", Toast.LENGTH_SHORT).show();

                         mWebview.loadUrl("javascript: {" +  "document.getElementById('SSR_CLSRCH_WRK_SUBJECT$0').value = '"+"temp1"+"';" + 
                         "document.getElementById('SSR_CLSRCH_WRK_CATALOG_NBR$1').value = '"+"temp2"+"';" + 
                         "document.getElementsByName('CLASS_SRCH_WRK2_SSR_PB_CLASS_SRCH')[0].click();" +
                         "};" ); // if I take out the click here the form will have temp1 and temp2 entered and everything fine, but it clicks temp1 and temp2 get cleared before it clicks some reason



                 }
            });


    }
}

Thanks for any help I appreciate it. Website where the form is located above if you need to take a look at it as well.

I suspect that document.getElementsByName is not supported. I suggest using document.getElementById since the link (button) has an "id" attribute.

Instead of

document.getElementsByName('CLASS_SRCH_WRK2_SSR_PB_CLASS_SRCH')[0].click(); :

Use:

document.getElementById('CLASS_SRCH_WRK2_SSR_PB_CLASS_SRCH').click();
