After running, i realise that on the home page, the services list drops down successfully but it doesnt do so when i'm on other pages. Can anybody help me?

I think the code and its structure is perfect. There is nothing absolute wrong with the code. Just uploaded the files onto the web and everything is working perfect. I checked plugins and all and i realised that the file only needs to be on the internet to run smoothly.
