Form Pre-Populated through Email

Hi Guys,

Does anyone has the same scenario as me？

there is a email has a hyperlink to my sign-up page which have a form on it.

if i am a receiver for this email, it's mean to i am a lead for database, then my information like firstname, lastname,emailaddress would be prefill to that form.

i use JQuery to get the value from URL:

Example:
http://info.marketo.com/test.html?FirstName={{lead.First Name:default=edit me}}&LastName={{lead.Last Name:default=edit me}}&Company={{company.Company Name:default=edit me}}&Email={{lead.Email Address:default=edit me}}

But i happend to a problem, if customer's first name like "Ben Rose", the copy of text version email will only make the link before Rose to linked, i lose the rest one, how can i figure it out?

I have no any idea at all.


Thanks,
Rose
