Everything I have read so far says this should work. For some reason the ‘base\_url’ value is never updated to the value passed in. Is there something obvious I’m missing? Thanks.

Hey @paulsc

Welcome to the community!! 👋

The syntax doesn’t look quite right to me, would this work?

```auto
--env-var "base_url=localhost:5000"

```

Just need to ensure that you have a variable in the collection called `{{base_url}}`.

@danny-dainton Thanks for the reply.

I should have mentioned I tried it quoted as you have it with the same result. I have a GET request that references {{base\_url}} and hovering over it shows the variables scope as Environment. I also tried setting it as a global and passing it as --global-var with the same result. I must be overlooking something obvious. Thanks.

Have you tried with a variation of variable names?

Try with `baseURL` or just `URL`, basically anything without the underscore in the name. Not sure it that’s impacting it but worth a try.

I have a reporter that shows which variables and values are used if that’s any use to you?

You can see the variables by using the `--reporter-htmlextra-showEnvironmentData` flag.
