 To implement inter-contract calling, you need to understand `sp.transfer` first. As the name suggests it transfers some data and amount to a destination contract(this is what calls the desired entry point).

 ```python
 sp.transfer(data_to_be_sent, amount_of_tezos, destination_contract)

 ## Intro
+
 We'll take a short detour from inter-contract calling to learn and explore a few other topics that will help you build the `Cryptobot` of your dream to absolutely dominate the war against the aliens 🤩
 
 In this one we'll cover a slew of different topics including `sub_entry_point` and `sp.for`.

 ### 1. Sub entry point

 Sub entry points allow you to define functions in a smart contract that can <span class="string-highlight">**ONLY**</span> be called from other entry points of the same contract.
 But why would you even need something like this?
+
 1. **Modularization** - Break down your code into different pieces to keep the code in your entry points clean and to the point. Makes the code easier to maintain and more readable.
 2. **Re-usability** - Once implemented, you can use them where ever needed. I think of them as **utility functions** that play a role in the success of other functions but aren't of much use indepedently.

 Sub entry points can access the contract storage - if your function doesn't need to access the contract storage, you should use [`sp.global_lamba` ](https://smartpy.io/dev/reference.html#_lambdas).

 ### Step by step walkthrough
 
 1. Modify `buy_powerup` in `Cryptobot`
-   * Modify `data_type` to also include `cryptobot_address` which is of type `sp.TContract` that accepts a record of string `power` and nat `duration`.
-   * Define `self_contract` - it's the contract that holds the details to `receive_powerup` entry point in `Cryptobot`.
-      * accepts a record of same shape as `active_powerup`.
-      * address points to `Cryptobot`( use `sp.to_address`)
-      * points to `recieve_powerup` entry point.
-   * Modify `data_to_be_sent` to hold `cryptobot_contract` as well, which is equal to `self_contract`.

 2. Implement `send_powerup` in `Market`
-    * Define `powerup_to_send` as the result of `find_powerup`.
-    * Make an inter-contract call to `cryptobot_contract` and send to it the `powerup_to_send`.

 3. Implement `receive_powerup` in `Cryptobot`.
    - Set `active_powerup` equal to the `poweup` being received as the parameter.
