VLANs on Dell N2048P Switches

Looking for some help here folks.

At my work, in our Admin office building, we have 3 Dell N2048P switches that we're wanting to test a VLAN for our Guest wifi network.

I went in and added the vlan to all of the switches. 2 are stacked, 1 on its own. I did not give it an IP address on the switches. I made sure the connecting ports between the switches themselves and the router were all set to trunk ports.

We use Ubiquiti APs since most of our locations are small offices. I set a VLAN only network up on the controller for those, and set the guest network to use that vlan only network.

Our Managed WAN provider set the VLAN(50) up on their Mikrotik router.

When I try to connect to the Guest network, I can't get an IP address at all.

Here is the config of both the stacked set and single switch.

!Current Configuration:

!System Description "Dell Networking N2048P, 6.2.6.6, Linux 3.6.5-50bbccb7"

!System Software Version 6.2.6.6

I'd appreciate any help. I've been with my employer for a little over 6 years now, and this is the first time I've been tasked with doing VLANs of any sort.
