I need help with the aid for Bruma quest I closed the gate outside skingrad I went back and spoke to the count but just keeps saying cnt help until the gate is closed also he won't come down In the main hall I have to go to his room how do I work through this? Thanks

From the UESP- "If you have started but not finished the Vampire Cure quest, you may be unable to secure Allies from Skingrad unless you manage to speak to Count Hassildor directly after closing the gate, as Hal-Liurz will refuse to talk about anything but the Cure, and so will not fetch the Count for you. If this happens, try waiting in the Castle Hall for a couple of hours - Hassildor should eventually come and find you himself."
Are you doing the cure quest? If this still doesn't help I would go somewhere else entirely and return in three ingame days I try that to fix everything.
If nothing works, if you are on the PC you could try "setstage MQ11 23". I had to use that to complete a buggy Fighter's Guild quest.

I'm on xbox and I have completed the vampire cure quest

Try waiting inside the hall for six hours at a time and see if he comes to you?

I had the same problem because I didn't close the right one. Try to close other gates around Skingrad.
