Product Configurator Script

Hi

We have a requirement where we need to fetch a string from Quote line item where the string will be combinations of LOV values of an attribute with comma as delimitor and restric the selection of LOV values of an attribute in e-config by user. Example :-

Media attribute has 5 values like X Y Z A B. In the quote line item field FeasMedia the value is X,Y,Z. Now when the user goes to the e-config and tries to select the value A for the media attribute an error is to be thrown but if the user selects any value with in X Y Z then no error to be thrown.
