@Lowlander, Thank you sir!

I can confirm, added as: https://www.ventismedia.com/mantis/view.php?id=21582

Sorry maybe I did not express myself correctly I meant I'm using $RightFrom(string,i)

$RightFrom(string,i) Returns everything after the occurrence of The character i
I copy pasted the line above from the Mask Reference table

This mask works well with other characters but does not work (for me) with the space character.

Hope this is clearer

Erratum above, please read $RightFrom and not $LeftFrom

Apologies for piggy backing on someone else topic, but I struggle with the use of Masks, I want to use $LeftFrom to remove the track number from a title:
e.g. title is "01 Title..." where there is a space after the numeral
$LeftFrom(<Title>, ) where there is a space after the comma simply does not work, the space is not recognized as such, is there a character to "escape" a space?
I'm on W10 / MM2024 1.0.3113

Thanks a bunch in advance
