Net Ionic Equation

Barfolumu

I am currently performing homework through an online application called ARIS. The program keeps telling me I'm wrong, so I'm stumped. The program can be finicky sometimes, so I wanted to post a net ionic equation to see if I was writing it correctly, and if I'm writing it incorrectly, please tell me where I'm making my mistake. Thanks in advance!

"Write the net ionic equation for the reaction between HBr(aq) and NH_3(aq)"

H^+(aq) + Br^+(aq) + NH_4^+(aq) + OH^-(aq) --> NH_4Br(aq) + H_2O(l)
