Fill forms with db result!

[eluser]WebbHelp[/eluser]
Hi!

I want to fill my form with data from the database.
The problem is if there is no row in the database then I got a error message you know!

<input type="text" name="head" value="<?=$query->head?>" size="50" />
<input type="text" name="title" value="<?=$query->email?>" size="50" />

This works, if there is things in the database, but if not, I got errors, how can I solve this?

Thanks //Webbhelp
