over 43 items in cart and the Auspost Module fails

Hi,

Has anyone had this problem and found a solution.

Cart with 43 items and the Auspost module calculates shipping fine.
Cart with 44 items and the Auspost module falls over.

Thanks,
Phil

This is really strange and I have to get it going cause I'm just starting to sell products through the web now.

Really, someone else must have this same sort of problem - this is a standard install of 1.4.9 and the auspost is the most up-to-date for 1.4.9 (opencart1491u4.auspost)

More info:

When I have dimensions (width, length, height) then the amount I can buy changes.
The amount also changes depending on the product I select - but it's not explainable.

For instance:
With dimensions I can select only 17 HQsoldering irons or 99 PicoDice or a few hundred IR-Emitter LEDs: So it seems to be based on weight.
But without dimensions I can select 43 HQsoldering irons or 43 PicoDice or 43 IR-Emitter LEDs: So it seems to be on the number 43.

I have the cart weight turned on and in both cases it is working out the weight correctly.

Does the Auspost Module add up the dimensions or something - this is my only explanation - it is sending the dimensions as well as the weight!

SOLVED but not happy

I had to make all dimensions of all products to 1cm and now it works fine.

Obviously no-one uses dimensions at all.
