    Close, but for a textarea you actually place the text between the tags, like this:

    <textarea name="comments" cols="25" rows="5"><?php echo $repvalue; ?></textarea>
    

    Also, you may want to clean the value of $repvalue with htmlenitites before outputting it, as any </textarea> tags in the variable will break your page.

    And as per charlietfl's comment you need to make sure your definition of $repvalue needs to be before you try to output it (nice catch, didn't even look at that).
