Formular to Extract Numbers out of a string

[Daniel_Smith]

I am trying to extract an ID number from a URL field. The number is at the end of the URL.

I have tried MID, RIGHT & LEFT but no luck.

The formula will need to:

• get the number only

• Ignore other numbers in the URL

• Get the number right of the last ‘-’

• Ignore a ‘/’ if there is one at the end
