rc1 to rc2 upgrade problem

[Forestshopkeeper]

I have completed the 22_ms2 to rc1 upgrade and am working on the rc1 to rc2 upgrade

In the instructions there is this section to insert into

catalog/shopping_cart.php

210 + $initialize_checkout_methods = $payment_modules->checkout_initialization_method();

211 +

212 + if (!empty($initialize_checkout_methods)) {

213 + ?>

214 + <tr>

215 + <td><?php echo tep_draw_separator('pixel_trans.gif', '100%', '10'); ?></td>

216 + </tr>

217 + <tr>

218 + <td align="right" class="main" style="padding-right: 50px;"><?php echo TEXT_ALTERNATIVE_CHECKOUT_METHODS; ?></td>

219 + </tr>

220 + <?php

221 + reset($initialize_checkout_methods);

222 + while (list(, $value) = each($initialize_checkout_methods)) {

223 + ?>

224 + <tr>

225 + <td><?php echo tep_draw_separator('pixel_trans.gif', '100%', '10'); ?></td>

226 + </tr>

227 + <tr>

228 + <td align="right" class="main"><?php echo $value; ?></td>

229 + </tr>

230 + <?php

 

I found the area, made the changes, but get the following error message when I go to the webs

Fatal error: Call to undefined function: checkout_initialization_method() in website/shopping_cart.php on line 231

I know the line numbers are different, but that is because of other contributions

Were does the function call on line 210 above get defined?

I found the problem. I needed to define the function in includes/classes/payment.php. that function was not listed in the version I had, and there had been no instruction to upgrade it.
