Trying to add free shipping coupon and now I'm getting error message when loading sit

I tried to add a free shipping coupon code to my cart (I'm using PowerStore v3.0) and I followed these instructions:

I added a set session variable "couponCode" to the cart page. I then did this:

On the discounts tab, create a new rule, set the trigger to:If Session Variable "couponcode" exists AND Based on Session Variable value: If the session variable "couponcode" has a value of "FREESHIP"

For the calculation, use Based on UPS Shipping rate value.

Then - I uploaded the new cart page and the new WA_Store_cart.php page. Once I did that, I could not load any page on my site. I received:

Parse error: syntax error, unexpected ')' in /home1/thelarse/public_html/WA_eCart/WA_Store_Cart_PHP.php on line 115

SO - I decided I'd undo what I did and come back here for help. Except that when I removed the discount code from the ecart setup, and removed the set session variable on the cart page - and then re-uploaded the two files - it didn't undo the error message...

Although - now the error message states that the error is on line 114, not 115.

We are launching the site today so I really need some help with this as soon as possible. Can you help?

The line that it's specifying is this (in the wa_store_cart_PHP.php) page:

//eCart Rule
112 function WAEC_WA_Store_Cart_USPSShipping() {
113 $totalShipping = 0;
114 if (true && ()) {
115 $totalShipping += floatval($_SESSION["WA_Store_Cart_USPS_Quote"]) + 0;//Result
116 }
117 return WA_eCart_FormatNumber($totalShipping, $this->ForceDecimalsC, $this->DecimalPlacesC);
118 }

I added the line numbers so you can see where it's pointing to (line 114) which is:
if (tru&& ()) {

What's going on? I undid what I changed.. I figured that my instructions weren't correct because they were given to me for PowerStore V2.0 and this is v3.0 which already has some coupon code setup?
