Applescript to remove "string"in Contacts social media field

Hi,

I am a newbie in apple scripting, and I am no getting it to work

In my contacts I have a field for Linkedin

In the linkedIn field, there is written linkedin://#profile/11111111

There are profiles empty

Profiles only with the number

and profile with the tekststring and number

I would like to remove in all cards for the field Linkedin : linkedin://#profile

So that only the numeric value stays

The rest needs to be untouched

Thanks for the help
