Hello, I am working with creating my own theme in order to get the Customer Web customized according to some requirements. It's the "New Ticket" I am working on. I have managed to get it working actually, the customer can see the customized web page I have created. Now, the problem I am having is that I don't know what files I should edit in order to get the desired result. I know I need to tweek quite a bit in order to get the desired look of my page. I want to hide some fields and that I can do. But when I hide the "To" field and the customer choses "Type", the "Service" drop down list becomes empty. It seems to be depending on some actual value in the "To"-field. Actually, the same happens if the customer chooses the actual service. Now, I assume that this is client-code, but I cannot find the actual code that react on selections of the drop down boxes. I assume there must be some "OnChange" function that I should find. Where can I find the files that do these kind of things, and preferable what file and which method to change? Also, when I have hidden the fields I want to hide, I need to set those values myself in some client side script. My plan is to do that in the "CustomerTickeMessage.dtl" file. Any comment on this would be appreciated. Thanks in advance! Regards, Niklas
