Weird Error when form submits

I get this error when my form submits and my thank you page does not come up..........The code is the same code I use over and over for many clients and now it is wigging out. Not sure what to do, I carefully compared working code to this form code and I see nothing that has changed.
Any ideas?

Here is the submitted content that I do receive even though the thank you page doesn't show up. Could it be that I am using a custom submit button(the only difference) and therefore that is why there is the submit x and y? How do I get rid of the xy?

Many thanks in helping me with this guys,

Diana

I'd like to see a copy of the contactus.php page giving the error. Most likely it is just a blank line of code or space that needs to be deleted on line 7.

Here is the page Ray................thanks!

contactus.php

see the following thread for details on troubleshooting the headers already sent error:

if you need further assistance, we would need a copy of the contact us php page so we can see the code, compress the file into a zip archive and attach that your reply.

Ray you were right, there was a space above line 7, removed it and all is well. Also removed the value and id names on my submit button which removed the extra xy submission fields.

Ahhhh, I can relax now. Thank you for pointing me in the right direction. I have made a note of this problem to remember it in the future.

Great day to all,

Diana
