Export Calculates Gross Total Incorrectly

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an invoice with the default template. Add multiple items.
2. Checking int he view of invoice shows correctly
3. Exporting to PDF etc. has an error as gross vlaue is 0.00

Please provide any additional information below.
I hacked a fix. I changed line 244 in templates/invoices/default/template.tpl

FROM
{{{
<td align="right" 
class="tbl1-right">{$invoice_gross_total|number_format:2:",":"."}&nbsp;{$prefere
nce.pref_currency_sign}</td>
}}}

TO
{{{
<td align="right" 
class="tbl1-right">{$invoice.gross|number_format:2:",":"."}&nbsp;{$preference.pr
ef_currency_sign}</td>
}}}

I'm not sure why it's being recalculated anyway considering the value has 
already been calculated in the DB by the invoice::getInvoiceGross function.

Thanks for reporting this.

What version of Simple invoices are you using and are you using the original SI 
invoice template?

Hi Matt,

Ah yes that might have been helpful! 2011.1 was the version and it was the 
original template.

Thanks.

Thanks, I can't replicate the problem but I will leave this open so that it 
gets checked again before the next release.

Thank you for contributing! :)
