Right here is where you are going wrong, unless what you have posted 
below is not an accurate representation of what you are doing. The 
action in your form is tp_update_tr.php and that is the *only* script 
where the $_POST variables are available.  You are (or appear to be from 
the code below) attempting to use them in the same script as the form. 
You need two scripts, a form script and a form-processor script.

[yes, I know you can do this in one script, but this is a good example 
of the issue raised earlier this afternoon about the occasional 
necessity for the simple version of an explanation.]
