edit add to cart button

After adding an Add To Cart button, if I try to edit it by going to behaviors and double-clicking on the "ecart add to cart" behavior, it brings up the Add to Cart menu, but after I make changes, it adds another button, rather than changing the existing one.

What am I doing wrong?

PS: Dreamweaver CS4.

What is the version of eCart that you are using and the OS that are working on? I have not seen this behavior myself but I will look into this further for you. Please post back with these details and any others that you can think of that might get me to experience the same problem.

I figured it out. I had tried to reposition the button, and by doing so, had inadvertently deleted the "form" line of code. This led to the described behavior. All fixed now.

Glad to hear that, I was very curious about the result you were getting. If you remove part of a server behavior it will often look like it is not on the page because of the way that the code for the server behaviors is translated by DW, but the code remnants will still be there.
