Got an errormessage

Hi,
I put the code

@import "remixins.less";
@base-font-size-px: 10;

at the beginning of my less file. After I added this I got the errormessage

Fatal error: Uncaught exception 'Exception' with message 'parse error: failed at if (typeof rmxsBaseFontSize == 'undefined') rmxsBaseFontSize = @{base-font-size-px}; return (parseInt(px.replace(/(^\d+)(.+$)/i,'$1')) / rmxsBaseFontSize + 'rem') };` /Applications/XAMPP/xamppfiles/htdocs/kirbytextil/assets/less/remixins.less on line 5' in /Applications/XAMPP/xamppfiles/htdocs/kirbytextil/site/plugins/lessphp/less.inc.php:3460 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/kirbytextil/site/plugins/lessphp/less.inc.php(2273): lessc_parser->throwError() #1 /Applications/XAMPP/xamppfiles/htdocs/kirbytextil/site/plugins/lessphp/less.inc.php(121): lessc_parser->parse('// ===== REM UN...') #2 /Applications/XAMPP/xamppfiles/htdocs/kirbytextil/site/plugins/lessphp/less.inc.php(753): lessc->tryImport(Array, Object(stdClass), Object(stdClass)) #3 /Applications/XAMPP/xamppfiles/htdocs/kirbytextil/site/plugins/lessphp/less.inc.php(284): lessc->compileProp(Array, Object(stdClass), Object(stdClass)) #4 /Applications/XAMPP/xamppfi in /Applications/XAMPP/xamppfiles/htdocs/kirbytextil/site/plugins/lessphp/less.inc.php on line 3460

I don't understand what I'm doing wrong. I load the less through lessphp could this a problem?

Best regards

On the lesscss website I read that lessphp can not compile if javascript is used because there is no access to a JavaScript interpreter. I think this is the problem.
Than I have to use remixing short before I compile a final CSS for the website.
