My client uses Google Wallet and I have a form setup to pass a dollar amount where the user can decide if they want to mail a check or continue on to Google Wallet to pay. I can pass a product price via the url and then insert that into the Google form. But what I would like to do is use either the Total field or if that doesn't work a Calculation fied that is basically just totaling the products. Everything I've tried includes a $ sign and that causes an error when you submit to Google.
Basically appending the product price to the url like {field name:FieldID:price} works because the $ isn't included. I'd like to to get the Total for all the products similarly without the $ sign.
