I have 2 websites online, which have the same code for receiving Paypal payments.
One is working OK the otherone does not show the shipping charge.

I am using the following code:
<input type="hidden" name="cmd" value="_cart" />
<input type="hidden" name="upload" value="1" />
<input type="hidden" name="business" value="business name" />
<input type="hidden" name="currency_code" value="EUR" />
....
<input type="hidden" name="handling_cart" value="<?php echo $trans_costs; ?>" />
etc.

When I put a fixed value for handling_cart it is showing the shipping costs.
The variable $trans_costs is available at this check out page, because it is possible to visualize with echo.

Is there any setting in my Paypal profile to change?
