Also, transactions only used to calculate fees must still have a fee set, though it doesn't have to be exact. The calculated fee will be included *the second time* this transaction is built (i.e. the transaction to sign and submit). This first time, only the fee parameter *length* matters, so here we choose a maximum value ([note](https://github.com/cardano-foundation/developer-portal/pull/283#discussion_r705612888)):

```bash
$ fee="300000"
```

We will reference the variables in our transaction to improve readability because we saved almost all of the needed values in variables.
