Attempting to Access index from a Array > Accessed No reading Structure, Help/Need Fix

I’m following Titanic Game’s Tutorial for RPG 
I’m stuck in these two videos

and

My issue is that in Set Style Widget it’s giving me errors

“Attempting to Access index from a Array > Accessed No reading Structure.”

From index 0-25

I searched the documents of unreal and in the comments the videos. As you see this guy been inactive for a bit.

One person posted a work around but I can’t seem to duplicate it when it come to the 2nd branch condition where the condition node was Item Type = “None” where is was a drop down menu letting one choose the preset item type.

Making the whole style widget look like this: Imgur: The magic of the Internet

These are my errors exactly:
