Parameter types how to manupulate string

I'm trying to use ref from parameter here but this is not working:

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Description": "Creating template to deploy 3 ec2 instances in 3 different AZs",
  "Parameters": { 
    "CFCidrVPC1": {
      "Type": "string",
      "Default": "10.10.0.0/16"
    }         
  },  
  "Resources": { 
    "VPC1": {
      "Type": "AWS::EC2::VPC",
      "Properties": {
        "CidrBlock": {
          "Ref": "CFCidrVPC1"
        },        
        "EnableDnsHostnames": "False",
        "EnableDnsSupport": "False",
        "InstanceTenancy": "default"
      }     
    } 
  }
}

CFCidrVPC1: This is defined in parameters and I'm trying to use it in resources but I'm getting Template contains errors.: Template format error: Unrecognized parameter type: string

I don't want to put in CIDR value directly while creating VPC.

Is there any way I can define CIDR somewhere and later reference it?

The Type should be String with a capital S.
