'no form has been selected' error after button click

[mcco...@molbio.mgh.harvard.edu]

I am using www::Mechanize to go to a URL:
$mech->get( "http://ppsp.biocuckoo.org/");

input text to text box:
my $name = "eppSeq";
my $value = ">gi|1621261
MGAAGDAAIGRESRELMSAAD";
$mech->field($name, $value);

select an option,
my $name2 = "KinasesLeft";
my $value2 = "3";
$mech->select($name2, $value2);

click on a button to choose the option:
$mech->click_button( name => "topLeft2Right");

then click a submit button:
$mech->click_button( name => "submit");

Everything is successful up until the last click_button, using $mech->success() all returns are 1 after each step up to the submit button. However, I get an error: click_button: No form has been selected at line indicating where the $mech->click_button( name => "submit") command is located. 

Does the form change after clicking a button ? 

If I comment-out the first 'click_button' command, then all seems to work.

The first click_button is an arrow button that takes what has been selected in one text box and moves it over to another text box. It is the top button in the middle between the two text boxes on the figure below. Highlighted in yellow.

->click_button() is a shorthand way of calling ->submit_form().

It looks like when you click that first button, it does some JavaScript. Mech doesn't know anything about JavaScript, so button actions that do JavaScript won't work in Mech.

You can use Google Chrome/Firefox Inspector and get the javascript form informations and do manually. It is pretty simple, https://developer.chrome.com/devtools/docs/network

Thank you.
