# Parse error: failed at $...

## Description

You get the error message `Unable to compile the theme "TcinnThemeWare...". parse error: failed at $...`

## Cause

Crucial here is the note "**parse error: failed at $...**". This means that a wrong value was entered in a configuration field and in which configuration field this is the case respectively the technical name of the field: **$...**

#### Example:

If the error message says `Unable to compile the theme "TcinnThemeWareBath". parse error: failed at $sw-font-family-base: ‚Open Sans', sans-serif; (stdin) on line 11, at column 1`, for example, the theme cannot be compiled or even saved due to an error in the `$sw-font-family-base` configuration field.

**Note**: If the error is not "`parse error: failed at $...`" but "**Undefined variable $...**" please have a look at this article: [undefined-variable](https://knowledge.themeware.design/knowledge-base/common-issues/administration/undefined-variable "mention")
{% endhint %}

## Solution

Just change the corresponding configuration field.

If you don't know which configuration field you are dealing with, just visit the ThemeWare® Config Finder and search there for the technical name `sw-font-family-base` (without the "$").

{% embed url="<https://config.themeware.design/en>" %}
ThemeWare® Config Finder
{% endembed %}

After you have adjusted the field, the theme or the duplicate can be saved and compiled again.
