I was trying to test out moving tokens between accounts, very ad-hoc and basic stuff on emulator network to get the hang of the language. When it came time to check for my account’s Vault Balance, I wrote a short script that prints the balance attribute of the Vault but it would not print anything to the console.

So I wrote the following script to test if log prints anything at all:

> pub fun main() {  
> log(“Hello World”)  
> }

and then I type the following command into the CLI

> flow scripts execute ./scripts/test.cdc

and this is the output:

> Version warning: a new version of Flow CLI is available (v0.27.0).  
> Read the installation guide for upgrade instructions: [Install Instructions | Flow Developer Portal](https://docs.onflow.org/flow-cli/install)

> Result: ()

Why is nothing being typed on the console? Is it normal to expect nothing to print on emulator? If I can’t get log to work, how can I check if my contracts and transactions worked properly?

Thanks and I apologize for the bad formatting, I’m not very good at this.

Update: Ok I realized that I can’t print to the Terminal in VScode so I just edited the function like this:

```
pub fun main(): UFix64 {
    ***Do stuff here***
    return VaultReference.balance

```

and my account’s balance is returned to the terminal.

When using the CLI, try using the -v flag. That might show the logs

flowjosh’s answer is correct, run the emulator with: flow emulator -v  
After you send your transaction, go back to the terminal window where you ran the emulator. Your logged messages will be there among all the other stuff it logs.
