In javascript use lowercase letters in object names

Parent => parent
Document => document
Document => document.body

try use e.g.

var parent = document.querySelector('[name="MAIN2"]');

for

<iframe name="MAIN2">...</iframe>

var parent = document.querySelector('#MAIN2');

for

<iframe id="MAIN2">...</iframe>

// Parent.MAIN2.Document.ENTRY1.PAGECODE.value="7"
//Parent.MAIN2.Document.ENTRY1.SUBMITVALUES.value="Continue.For MANUFACTURER DETAILS"

var parent = document.querySelector('#MAIN2');
/*
  <form id="ENTRY1">
    // ...
    <input id="PAGECODE" ...>
    <input id="SUBMITVALUES ...>
  </form>
*/
parent.document.querySelector('#ENTRY1 #PAGECODE').value = '7'; // I'm guessing: <input id="PAGECODE">
parent.document.querySelector('#ENTRY1 #SUBMITVALUES').value = 'Continue.For MANUFACTURER DETAILS'; //  I'm guessing: <input id="SUBMITVALUES">
