Powerstore Change gateway to First Data

I am also trying to change the payment gateway on PS3 to FirstData using eCart5.

In going through the steps in the PDF referenced in an earlier reply, there are some steps that are left out, so I'm not sure how to proceed. My first two attempts at this resulted in there being no "Payment Info" area on the checkout page to enter credit card information...

Just in case others need this same help:

Question 1:

On page 3 of the PDF, step 8 says "Proceed through the wizard, completing the various options when necessary." There are 4 more steps in completing the wizard after pointing to the success and failure files (step 1).

Step 2 has a few values that need to be customized. The first being "configfile" where you enter the six- to ten-digit number assigned at merchant account setup.

After entering the number, do I click the lightening bolt to the right of the field? (I didn't) If so, what do I select in the pop-up window?

Question 2 (Still step 2):
The next value to change is "keyfile" where you reference the PEM for your store. The value it has there is <?php echo realpath("../linkpoint/test.pem") ?>

I am pretty sure I should change "test.pem" to the name of the PEM I received from FirstData, but I can't find a "linkpoint" folder anywhere on the site, so I created one in the site root and copied my PEM file to that folder.

Is this correct?

---------------

I didn't make any changes on step 3 and unchecked the option to use PayPal on step 4.

In trying to determine what's going wrong, I noticed that at the top of the code in confirm.php in the //WA eCart Includes, there is this line:

<?php
require_once("WA_eCart/Adv_CO_Scripts/LinkPointAPI_PHP.php");
?>

If I look at that file, lines 4-7 read:

$keyfile = "";
$host = "";
$port = "";
$outXml = "<order>";

Should there be any data between the quotes in keyfile, host & port? Or I guess what I"m asking is, should the wizard have put the info I entered in there?

I wish I could attach my confirm.php file to this post, and a text file of the whole thing is too large. I have made five TXT with the confirm.php code in case you want to see it.

Thank you, in advance, for your patience & help!
