Getting a zero value from text field

Question

Hi,
The form has 3 text fields for Freight areas, the viewer inserts "1" in the field that is applicable to their area.
The first 2 fields have a cost of $10.00 and $15.00 and the third is for pick up so there is zero cost. If they insert "1" in either of the 2 fields, it shows up as 1 in the returned email to to the site owner and to the viewer but I can't get the free freight field to display anything in those returned emails.
I've included the PHP form handler file and the site address is: http://www.hamdenestate.co.nz/test-site/contact-us.html
Thanks.

But wouldn't it be much more intuitive to use radio buttons here?
Yes, but this a bit of a long running issue. The OP ideally wants to add the freight cost to the total price at the bottom of the form on the website before the information is sent back via php but that is done using javascript and radio buttons mess with the calculations. Inserting 1 into the freight form fields, which is counter-intuitive, does the trick but that will mess with the total price when php collects the information because the value is 1 rather than 10 or 15.
