Need sidebox to appear on 1 page only

Hi folks

Just need some programming advice.

I'm adding a custom sidebox to my "billing" page (to include payment FAQ).

I downloaded the kuroi's "blank sidebox plugin" from the addons page, and have modified it with the advice from here.

However, I'm not entirely sure what the code should look like in terms of replacing the link. The tutorials code looks like:

if ($this_is_home_page) {

the link on my billing page (where I want the sidebox to appear) looks like:

..../index.php?main_page=no_account

...due to using Numinix's Fast and Easy Checkout plugin, set to COWOA.

I tried changing the code to:

if ($no_account) {

...but that didn't seem to do much (the sidebar isn't even showing at the moment).

I presume it's something incredibly simple - someone care to help?!

I'd really appreciate it!

Regards,

Seven

I'll answer my own question. This works for me, not sure if it's the correct way to do things (not a programmer), but I'm happy....

  if (in_array($current_page_base,explode(",",'no_account')) ) {
    $show_billing_questions = true;
  } else {
    $show_billing_questions = false;
  }

If anyone else is looking for a solution, there it is.
