Based on the value in AF, delete some of the contents of H

Good Afternoon

I am looking to ensure that the contents of column AF, which can have mulitple values, pulled from a sharepoint site, only has the value associated with the value in column H. I like this to work through all of the rows in the spreadsheet.

Example

H contains: Apple
AF contains: Apple=2, Orange=3

I would like to end up with AF containing: Apple=2

Many thanks

Wow

Do I need to change any of this to look at my specific columns? I have put this into a module, what is the correct way to use this?

Many thanks
