[Tutor] New Problems with script

Fri Jul 22 03:24:28 CEST 2005

Hi,

First of all, try to include the relevan code *inline* instead of 
attaching. This creates all sort of problems, specially that it prevents 
the list archive from gracefully displaying your message.

You have this:

print "#blend {
     width: 10em;
     padding: 0;
     border: 1px solid black;
     margin-left: 3em
}

Double quoted strings cannot span more than one line, you should use 
triple-quotes instead.

In any case, you should try to run it outside the CGI environment to see 
what's wrong. In this case, you should have got a simple syntax error if 
run from the command line... if run from a CGI, it is more difficult to 
debug.

Hope it helps,

Hugo
