Shipping per unit/weight not calculating for more than one item

I have set up my shipping to use the Per Item/Unit Weight and I have it set to use the amount in the weight for the shipping cost.

For Ex:
I have the weight of an item at 10.00 - it will charge $10 shipping per item.

The problem is when someone tries to purchase more than one item, it is supposed to add 10.00 per item but it's not. How can I fix this??

My site is http://www.upm75.com

TFYI his is where I got the idea to do it that way...
https://www.zen-cart.com/tutorials/index.php?article=208

Were you able to fix this?

I add to cart and my shipping appears to be the quantity * products_weight * unit rate ...

Not fixed yet....
If you try to order 6 of the UPM 75 pitching machines, the shipping should be $120 ($20 per unit x 6 = $120 total) When you go through the checkout process it makes the shipping $185????

Could you check your settings in the Configuration ... Shipping/Packaging ...

Set the values for:
Maximum Weight to 5000
Both Tare Weights to 0:0

It is all set that way and still does it.....

I get the right calculations of 6 x 20 = 120 ... not sure what to tell you ...

Are you going through the entire checkout process (up to where you would confirm the order). The shipping estimator tells you the correct amount, it's when I go through paypal to pay and when I get to the page where I would confirm my order is when it tells the wrong amount.

Does this happen on the Zen Cart shop or on the PayPal Page?

I go to the:

checkout_shipping $120.00
checkout_payment $120.00
checkout_confirmation $120.00

I'm not sure? I think it might be the Paypal. When I go to check out I click "checkout" and then it goes to where you click the "Paypal Express Checkout" and then you sign into you Paypal, you go to next and it comes back to Zencart and you would click "confirm" to finish the payment. That is when the shipping is incorrect.

I go to PayPal and come back with $120.00 shipping on the checkout_payment page and then on the checkout_confirmation page ...
