# Unable to compile the theme...

## Description

You get the error message `Unable to compile the theme "TcinnThemeWare..."` in the theme configuration.

<figure><img src="/files/oSOGZdrToEsITJ31vCAq" alt=""><figcaption></figcaption></figure>

## Cause

There are several possibilities here, because this error can be caused by an unknown variable in a configuration field or by an incorrectly filled configuration field.

* Unable to compile the theme "TcinnThemeWare...". Undefined variable $...
* Unable to compile the theme "TcinnThemeWare...". parse error: failed at $...

In addition, there are new error messages due to the new validation of the theme configuration from Shopware 6.6.9:

* Unable to compile the theme "TcinnThemeWare...". Error: argument \`$color\` of \`red($color)\` must be a color
* Unable to compile the theme "TcinnThemeWare...". $color: 0 is not a color
* Unable to compile the theme "TcinnThemeWare...". $color2: 0 is not a color

## Solution

The part directly after the message `Unable to compile the theme "..."` is decisive. It says `Undefined variable $...` or `parse error: failed at $...` or a reference to the variable `$color` or `$color2`.
