[Heat] Reg accessing variables of resource group heat api

Hi , We are developing heat templates for our vnf deployment .It includes multiple resources .We want to repeat the resource and hence used the api RESOURCE GROUP . Attached are the templates which we used Set1.yaml -> has the resources we want to repeat Setrepeat.yaml -> has the resource group api with count . We want to access the variables of resource in set1.yaml while repeating it with count .Eg . port name ,port fixed ip address we want to change in each set . Please let us know how we can have a variable with each repeated resource . Thanks, A.Nanthini
