# TFNFR13 - Default Values with coalesce/try

Module Specification for the Azure Verified Modules (AVM) program

ID: TFNFR13 - Category: Code Style - Default Values with coalesce/try The following example shows how "${var.subnet_name}-nsg" SHOULD be used when var.new_network_security_group_name is null or ""
Good examples:
coalesce(var.new_network_security_group_name, "${var.subnet_name}-nsg") try(coalesce(var.new_network_security_group.name, "${var.subnet_name}-nsg"), "${var.subnet_name}-nsg") Bad examples:
var.new_network_security_group_name == null ? "${var.subnet_name}-nsg" : var.new_network_security_group_name)
