the first one compares the values
the second checks the result of setting the value to "credit"

I suggest you use $_SESSION['section'] instead of $HTTP_SESSION_VARS['section']

$HTTP_SESSION_VARS["section"] = "credit" is an assignment. You overwrite or set the content of variable $HTTP_SESSION_VARS["section"]  to credit. If youse in an if-statements it's typical a typo/bug

$HTTP_SESSION_VARS["section"] == "credit" is a comaprison if variable $HTTP_SESSION_VARS["section"] contains the value "credit"

this seems to break my code?

      if ($_SESSION["section"] == "credit") {
      $_SESSION["var1"] = $frmloanamt;
      $_SESSION["var2"] = $loanterms;
      )

What does it mean to be "Always On"?

what do you mean by breaking your code ?

Also to note that $HTTP_SESSION_VARS["section"] = "credit" is allways true when used in side if, as "credit" is a true value in php.

by break your code do you mean it doesn't execute the statements in the if statement? This is probably because $_SESSION["section"] == "credit" evaluates to false, try and echo out $_SESSION["section"] and see what value it contains.

The problem with:
 if ($_SESSION["section"] == "credit") {
      $_SESSION["var1"] = $frmloanamt;
      $_SESSION["var2"] = $loanterms;
      )
is that you have a closing parenthesis instead of brace }
Try:

session_start();
$_SESSION['section'] = 'credit';

 if ($_SESSION["section"] == "credit") {
      $_SESSION["var1"] = $frmloanamt;
      $_SESSION["var2"] = $loanterms;
}

On another note:
if ($HTTP_SESSION_VARS["section"] == "credit")
means: "is $HTTP_SESSION_VARS["section"]  equal to 'credit'?"
However:
if ($HTTP_SESSION_VARS["section"] = "credit")

is equivalent to the following two statements:
$HTTP_SESSION_VARS["section"] = "credit";
if( $HTTP_SESSION_VARS["section"] )
