Custom Add To Cart Module - Not Working With Logged In Users

[tawalu]

I've created a custom module that allows users to customize their item with a visual interface. After customizing there is a submit button that saves the customization using a jquery ajax post request to the item's url and then uses the jquery submit command to submit the form. The user is then taken to the shopping cart summary screen.

 

The module works as intended when a user is not logged into an account. However, if the user is logged into an account the customization information is saved, but the item is not added to the cart and the user is redirected to the store's homepage.

 

Is there something different about the way the add to cart submit function works when a user is logged in vs. a non logged in user?

Here is the js function I am using to handle the submission.

$.ajax({
	      url: URLOFITEM,
//Customization info as object
	      data : dataObject,
	      type : "post",
	      success: function(){
	      	//Adds to cart
	      	 $("#buy_block").submit();
	      }
	    });
