MSRP Add On - Not On Front Page

Hello everyone,

I just installed the MSRP Add On and I don't want to MSRP to show on the front page. I want it to show on the order pages, but not the front page.

This is the website. Take a look. RC-Access.com

So, my question is how to make the MSRP not display on the front page?

If you want absolutely NO Prices to display on the Home page of your site, you could customize the display price function:

////
// Display Price Retail
// Specials and Tax Included
  function zen_get_products_display_price($products_id) {
    global $db, $currencies;

    $free_tag = "";
    $call_tag = "";

// do not show prices on home page
    global $this_is_home_page;
    if ($this_is_home_page) {
      return '';
    }

I don't understand Step 1 of the mod for MSRP. What exactly do we put in the SQL query under admin? I put in what is indicated in step one and I get errors.

This is what I get -

1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'tableprefix_products ADD products_msrp DECIMAL( 15, 4 ) NOT NULL AFTER products' at line 1
in:
[ALTER TABLE zen_ tableprefix_products ADD products_msrp DECIMAL( 15, 4 ) NOT NULL AFTER products_price ;]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

What is the correct verbiage that I am supposed to use to get this part to work?

I am using version 3.8

Please advise. I would appreciate it. Thanks
