Request Property to Personwantsorg

Hey,

I have a problem with a request property. I read an old post about request property and PWO that said if you name the parameter in the request property the same as the FK in the table PWO it should automatically fill this in the table. But this is not the case for me. I have tried this one different columns in the table PWO and tried making a new column etc. But nothing works. There is not a single value coming from the request propety... What am I doing wrong?

Lets say the value is CCC_random in both request property and in PersonWantsOrg. The value in request property is calculated btw, so I can use a person from my table
