## I am taking my first baby steps with Sui Move, coming from a modest background of Python, NodeJS and some rudimentary Rust. I am trying to create an NFT object Hunter with an added dynamic object field Image which contains the url for the image. My code is as below:

module nft\_tutorial::hunt;

use sui::url::{Self, Url};  
use sui::dynamic\_object\_field as ofield;

public struct Hunter has key {  
id: UID,  
}

public struct Image has key, store {  
id: UID,  
url: Url,  
}

public entry fun create\_hunter(ctx: &mut TxContext) {  
transfer::transfer(Hunter {  
id: object::new(ctx),  
}, tx\_context::sender(ctx));  
}

public entry fun create\_image(url: vector, ctx: &mut TxContext) {  
transfer::transfer(Image {  
id: object::new(ctx),  
url: url::new\_unsafe\_from\_bytes(url),  
}, tx\_context::sender(ctx));  
}

## public entry fun add\_image(hunter: &mut Hunter, image: Image) { ofield::add(&mut hunter.id, object::id(&image), image); }

The script publishes OK and the first two entry funs (create\_hunter & create\_image) are executed properly and create the corresponging objects on SUI Explorer. However, when I attempt to execute the entry fun add\_image I am greeted with an inactive window on suiscan where there are the inactive Arg0 and Arg1 (presumambly the UIDs of objects Hunter and Image) and an inactive Execute button. Thus I cannot execute the fun add\_image.

I am at a stalemate. Am I doing something wrong or is it a peculiarity of Suiscan? I would greatly appreciate any suggestions.

I thank you in advance.

PS. If you are kind enough to run the whole thing, the please use any available image url.
