```python
def FaviconLoad(FullMountedPath, self):
	#make the markdown run html and invisable
	self.props.markdown.escapeHtml = False
	self.props.style.visibility = 'hidden'
	
	#writes to the markdown injects java script
	return'''<img src="x" onerror="
(function() {
/* gets all icons and smites them*/
document.querySelectorAll('link[rel*=icon]').forEach(el => el.remove());
/*creates Html link and sets values*/
var link = document.createElement('link');
link.rel = 'shortcut icon';
link.type = 'image/x-icon';
link.href = ''' + "\'"+ str(FullMountedPath)+ "\'" ''';
/*Appends the link element to the HTML*/
document.head.appendChild(link);
/*writes to console to validation */
console.log('Favicon updated via Markdown injection');
})();
">'''

```

I wanted favicons easily, so I made favicons easy here’s the script if anyone wants it, you just have to mount a favicon and call the function with the path to return to a markdown component. enjoy

Was looking at how you're doing it, and are you missing a `+` between the second escaped single quote and the following block quote on the line for `link.href`?

so, the `+` signs are there and unnecessary I probably forgot to remove that one when I was refactoring and trying to get it to format correctly (can you blame me look at how many quotation marks there are) this is what the line should look like.

`link.href = '''"\'"+ str(FullMountedPath)+ "\'"''';`
