Where are you seeing this? In an attributes grid? If so you need to go to Magento Admin > Catalog > Attribute > Manage Attributes and set "Visible on Product View Page on Front-end" to no.
Hi! Thanks for the reply! The weight shows on each of the products description page. When I checked Magento Admin > Catalog > Attribute > Manage Attributes >Weight>Frontend Properties>Visible on Product View Page on Front-end...it was already set to 'NO'
Ok it that case it looks like your theme is printing out the weight specifically. You need to use template hints http://help.sweettoothrewards.com/article/434-how-do-i-turn-on-template-path-hints to figure out what file is doing that and then update the file.
