Syntax error

Just made a shipping rule change, using the eCart Interface.
Browsing page I get this error: Parse error: syntax error, unexpected ')' in C:\Inetpub\vhosts\......\httpdocs\WA_eCart\eCart1_PHP.php on line 95

Viewing the code in Dreamweaver it tells me:
There is a syntax error on Line 95.

//eCart Rule

function WAEC_eCart1_HST()  {

  $totalTax = 0;

  if (true && ()) {        LINE 95

    //Result

  }

  return WA_eCart_FormatNumber($totalTax, $this->ForceDecimalsC, $this->DecimalPlacesC);

}

//eCart Rule

Note, I made a shipping rule change, this is a tax rule. The tax rules precede the shipping rules in the page.

the error is the there is not trigger:

if (true && ())

the empty parenthesis are the syntax error.

when creating the rule what did you enter for the rules trigger?

I attached the entire page to the previous post.
The trigger for the shipping rule I just added is the presence of a specific item in the cart.
The trigger for the Tax rule that is causing the failure was the existence of a Session Value but that seems to have been completely overwritten!
Very disappointing!

Yes, I saw the page attached to your previous post, but that doesn't tell me anything except what we already know:
There's a Syntax Error

The code does not tell me anything about the settings used for the tax rule to generate the code with the Syntax Error, hence my question.

Perhaps if you could send a screen shot of the tax Rule and the trigger you are using, i can tell why the code is being generated incorrectly.
