showing product number in the item window

here is the issue i have used the guide and did the thing where we modified the CSS in the display properties where it remove the line below...

.hikashop_product_code_main{ display:none; }

but the only problem is that it displayed the product weight not the product code. is there some way we can address this..
I really liked where the numbers showed up i would just like for them to be the proper numbers. thanks a bunch

Well that was just the trick to get things working for the most part but that has lead to another problem which i am hoping you can provide the solution to. I have started using the related products tab which is amazing by the way however there is a slight display problem which is displayed in the attached photo.

i need some way to space the buttons from the item code on the display. and yes i am using the Hika shop CSS buttons

Please forgive my ignorance but where do i put this line at ??

never mind i found it.....
