Help, how can I change the price of an old buy, sell, trade?

I created an a thread to sell a script and I want to change the price (or create a new one). When I create a new one it does not come up and I don't know how to change the price (the post is old I want to change the price and bump it).

PM me if you can help

Thanks

Report your post,Ask Mod to change it .

 

You can't.

 

Make a post in that thread... w/ the new price

 

I guess I can do that but I did not want to double post, and also the 1st thing they will see is the old price . I guess for now that will do.

Thanks
