Setting attributes to my products !

Can any body tell me why I'm getting this on the attributes drop down and how to fix it ?! As I wanted to set the weight of my product by 1 Kilo - 3 Kilo, but I couldn't manage to set that correctly plus I got this problem ! any ideas ?

Probably a corrupted, missing or improperly edited copy of includes/languages/english/product_info.php, which is where those are defined.

So you think I need to upload the product_info.php once again ?

OK I did that and it worked out with me .. thanks ..

It's working now but after ( add this to my cart ) how I can I keep the weight dropdown menu active rather than having it fixed/text as it shows in the attached print screen, It's very handy for the customer to be able to change the amount of kilos at that stage!

You can't do that in the stock Zencart code - you would have to write something yourself.
