add to cart but stay on same page

I have a customer who has 2 shops that I have just taken over
Both shops on the product listing page have add to cart buttons with quantity boxes however one will flash a green message when a product has been added to the cart and stay on the same product listing page but the other will do the same apart from it goes to the product info page of the product I have added to the cart where it displays the green added to cart message.

I'm sure there is something in the admin that is different between the 2 shops but can't find it.

Could some kind soul point me in the right direction

Thanks

Admin > Configuration > My Store > Display Cart After Adding Product

That stops the customer from being taken to the cart which is working but how do I stop the customer being taken to the product info page so that they stay on the product listing screen

I didn't design this so I apologise in advance

What you've described as what you want, is what I believe it should do. Do you have a specific example where it doesn't do this that I could look at?

It uses the column listing for product listing mod and I have just uploaded the files for this mod again just be sure but it still takes me to the product info page

Thanks for trying to help me out by the way

More questions:

• Do these stores have different product types?
• Do you have "Display Product Add to Cart Button" = 2 and "Display Multiple Products Qty Box Status and Set Button Location" on both carts?
• Has the section after the comment "// qty box with add to cart" been modded in the modules/product_listing.php file on the babyshowerhost site?

I think I broke it when upgrading to 1.3.7.1
Forgot to mention that, sorry

All products are of same type
Display Product Add to Cart Button is set correctly
Product Listing module is the one from the column mod

I think it's probably down to an older template being loaded and I'll just have to have a play until it works as it is supposed to.

The babyshowerhost site is 1.3.5
Trouble is the people who set the site up were complete muppets so I don't know if they fully utilised the over ride system and they have added about one hundred new styles which are completely unnecessary.

I'll give it a final shot but the cklient may just have to live with it until she wants the site to look half decent.
