Greetings, 

I'm using subst_hf() function to do some search and replace and i want to identify a undifined amount of digits after a string (ex: string=123123). Everywhere i look, the right way seems to be \d so i'm doing subst_hf("Via","/;string=\d/substitution_string/", "a");

It doesn't seem to work. Any ideas why? 

Best Regards,
