Diffuculty with sweeps from the guard

I recently started training in BJJ and I have been having trouble sweeping people from my guard. My teacher has showed me multiple sweeps on just as many occasions and I drill them yet I continue to have diffuculty with them. Any advice would be greatly appreciated.

Just realized. Sorry about being an asshole and posting this here

In the future, instead of starting another thread, wait for a DHS mod to take care of it.
