Undefined offset Notice

I can confirm this bug under latest drupal dev 7.11 and drupal commerce 7.1.0

Can also confirm I get this same message.

Same here. PHP 5.3

A quick solution to hide the notice is to change line 68 of commerce_google_analytics.module from:

$tax_sum += commerce_currency_amount_to_decimal($tax_component[0]['price']['amount'], $tax_component[0]['price']['currency_code']);

to:

$tax_sum += @commerce_currency_amount_to_decimal($tax_component[0]['price']['amount'], $tax_component[0]['price']['currency_code']);

This occurred for me when a tax rate is not applied. If the tax is not applied, then $tax_component[0]['price']['amount'] never exists.

The specific example on our site is that we ship to two countries - Australia and New Zealand.

Australian tax is applied to orders shipped to Australia
New Zealand tax applied to orders shipping to New Zealand

So for each order, one tax is not applied.

See my patch which adds a condition to first check whether the tax has been applied or not.

This still needs to be reviewed please.

Commited in new 7.10 release

Looks like this fix wasn't commited
http://drupal.org/node/1136656/commits

Error still occurs in 7.x-1.0.

Actually the patch needs to be rerolled.
Also removed some extra whitespaces.

Here is the same patch as above but without the extra spaces, and adds a period to the end of the comment (proper Drupal coding standards).

This patch (and the one above) works for me.

Thanks ppl! Committed and pushed in the dev release for now.
