embedding iframes in wordpress

[rueschhoff]

I want to embed an iframe in wordpress and tried a plugin but it didn't work

they also provided me with some php code -- but not sure how to use it

<?php
require("/home/rueschho/public_html/instantformpro/instantformpro.php");
$ifp_param['form_id'] = 1;
$ifp_param['base_path'] = 'http://ericarueschhoff.com/instantformpro/';
display_instantformpro($ifp_param);
?>

and then this is the iframe code

<iframe height="1636" allowTransparency="true" frameborder="0" scrolling="no" style="width:100%;border:none" src="http://ericarueschhoff.com/instantformpro/embed.php?id=1" title="PR Questionnaire">PR Questionnaire</iframe>

Any help would be greatly appreciated!!
