JSON Schema dependency based on minimum value - json

Question

I am trying to add a dependency to a property based on the property value before it. Within my JSON, there is an instances property. If that property is > 2 only then show the StartIndex property. I have tried adding another if-then-else to my pre-existing one (wrapped in an allOf) but that was failing so I decided to take the dependency route.
Here's the JSON Schema with my attempt at adding the dependency withing the StartIndex property:

UPDATE: So I actually figure this out using nested properties as shown here

],
"pattern": "^(.*)$",
"title": "Start Index for these VMs",

}
},

"NO"
