Capture key for use in next insert

Question

Ok, I have a form that would probably be beyond what most people use ADDT for, but it works!
Here's a really long form, and it does these steps.
1. Register's user.
2. Runs custom transaction (or trigger, forgot) that contacts authorize.net, charges a credit card and returns pass or fail
3. Inserts a line in a table that shows they have credit in our store. Line has a uid_usr field that is connected to user registration via link-transactions.
4. Inserts a line into same table that gives them a starting balance, again link-transaction for uid_usr... BUT there's a second field credit_used_cre that should be a foreign key to step 3's id_cre...
What I would like to do is capture the ID returned from Last_Insert_ID() in step 3 and pass it as something like {GLOBALS.id_cre} But I'm not sure how to do that. THIS is where I need help.
5. I store the credit card info into payment_pay. Again, linked to users_usr.
6. Insert a starting balance into sbal_sbl, linked again.
7. Do a custom transaction that goes back and updates a few dates in the above directly with SQL.
SOOOOO, how do I capture an ID to a variable so I can reuse it in a future transaction??

It sounds to me like Hanno's attempt is not in his code using $insertKey = $tNG->getPrimaryKeyValue(); but in his calling of it. When I get that error it's because the function doesn't understand what $tNG is.
In my trigger, I have:
function Get_Credit_line_ID(&$tNG) {
global $credit_line_id, $connShop, $uid_usr;
$uid_usr = $tNG->getPrimaryKeyValue();
//end Get_Credit_line_ID trigger
(I would get scope errors if I didn't call global $connShop.)
And let me know if you've ever done this many triggers at once before:
// Register triggers
$userRegistration->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "KT_Insert1");
$userRegistration->registerTrigger("BEFORE", "Trigger_Default_FormValidation", 10, $formValidation);
$userRegistration->registerConditionalTrigger("{POST.password_usr} != {POST.re_password_usr}", "BEFORE", "Trigger_CheckPasswords", 30);
$userRegistration->registerTrigger("AFTER", "Link_Insert_Initial_Credit_To_User_Registration", 40);
$userRegistration->registerTrigger("ERROR", "Link_Insert_Initial_Credit_To_User_Registration", 40);
$userRegistration->registerTrigger("AFTER", "Get_Credit_line_ID", 44);
$userRegistration->registerTrigger("AFTER", "Link_Insert_Payment", 60);
$userRegistration->registerTrigger("ERROR", "Link_Insert_Payment", 60);
$userRegistration->registerConditionalTrigger("{POST.pay_up_front} != 'y'", "AFTER", "Link_Starting_Balance_to_Credit", 70);
$userRegistration->registerConditionalTrigger("{POST.pay_up_front} != 'y'", "ERROR", "Link_Starting_Balance_to_Credit", 70);
$userRegistration->registerTrigger("AFTER", "Link_Insert_Sbal_into_Sbal", 80);
$userRegistration->registerTrigger("ERROR", "Link_Insert_Sbal_into_Sbal", 80);
$userRegistration->registerTrigger("AFTER", "Trigger_WelcomeEmail", 90);
$userRegistration->registerTrigger("AFTER", "Process_card", 50);
$userRegistration->registerTrigger("END", "Trigger_Default_Redirect", 99, "../../login/customlogin.php?kt_login1=1&kt_login_user={POST.username_usr}&kt_login_passw ord={POST.password_usr}&kt_login_rememberme=1&redir=".urlencode('/credit/apply/step2.php') );
Oh and btw, I NEVER COULD get the log in user after registration tutorials to work, so I hacked together a login pay that logs them in and redirects them where I need them.
