Python : Pre fill form field with value of variable

I have a cgi  page which contains an html5 form . This form should have the top field pre filled with the value of a variable
Delta_euro_total.  The value of this variable is available as you can see from the attached image of the page output. However, only the variable name is being pre filled.

I am attaching the code for the CGI page.  Line 134 starts the function definition Page() which is called later in the code - line 256.

The problem must be with the syntax used in the function.  Hopefully is is obvious to the experienced eye !

Thanks for your help
