Your question is very hard to follow. I think the second part you are actually asking about javascript but i am not sure. Something like when a user enters a text description for a title in your form, another html form field is automatically filled? Or are you asking how to do this on the backend inside the perl cgi? Both ways will work but each require a different solution.

The first part i think maybe the value is being set correctly but you can't see it because you are outputing the result and viewing via html which means the value"<font size=4>" is not viewable unless you view source code?

Please note that html questions do occasionally get answered here if they are clearly written. Spend a little more time on your question. Make sure it is very easy to follow. I have asked questions here before which take hours to compose. It's the only way i can be sure and get a good answer.

Good luck
