I'm having the same problem and not able to find answers anywhere online as to why.  It just says {Your Name} in both the admin and the senders email.

I am having a problem with the {Your Name} variables showing the proper value in both confirmation and admin emails.

 

In the confirmation emails it does not appear correctly in the subject or the body of the email. It only shows {Your Name}

 

in the Admin, it works in the body and shows the users inputted name, but in the subject it shows {Your Name}

 

I can't seem to figure out why this is doing that. I didn't change those varaible from the defaults?

 

Any ideas?

I found a solution. I'm running WPMU 3.2 and spent about 2 hours trying everything with no luck until I checked the suppress tracking and DB option, clicked update settings, then unchecked it and updated settings again and all variables were working in the subject and everywhere else. Hope this helps everyone else out. Good luck.

Hi Rembrandt,

your solution dont work! have any one else tried it?

Warm regards Anders

I had issues with this working, too, but resolved as follows;

I noticed that Ajax wasn't enabled

Then I noticed that I had ticked the 'multi-form' tick box. 

I turned this off, and enabled Ajax, at which point the form variables worked in the email subject line. I am not sure whether it was the Ajax or multi-form option that stopped it working.
