Network Install: Child-theme not working correctly

I’ve implemented a child-theme. Followed all the steps in the coded, but it’s not completely working. I changed the sidebar.php template in my child themes directory and it’s working on the website. I can set the theme and see it as superadmin and admin. Unfortunately, my CSS changes aren’t displaying on the front-end. Even when removing the @import, it makes no difference. Anyone got any ideas as to why it’s refusing to do this?

I’ve installed wordpress as a network on a main domain and two subdirectories. I’m using the panorama theme as the main theme and making childs from it.

/*
Theme Name: panorama-technology
Template: panorama
*/

@import url("../panorama/style.css");

.post h2 {
color: F98;
font-size: 250%;
font-weight:100;
padding: 0 0 5px 5px;
margin: 5px 0 5px 0;
background: #fff url("images/dots.gif") bottom left repeat-x;
}
