Question: I'm trying to create an exclusion script that will not send to people who do not have at least 16 matches in a related DE. I feel like i'm really close but haven't been able to get it to work yet. 

This is what I have so far:

```
%%[ROWCOUNT(LOOKUPROWS("Shane_RA", "family_ID", _subscriberkey)) > 15]%%

```

Answer: 
It assumes it's a AMPScript block. All you need is this without the block syntax:

```
ROWCOUNT(LOOKUPROWS("Shane_RA", "family_ID", _subscriberkey)) > 15

```
Remember, your DE `Shane_RA` should be using template as DomainExclusion (Shown in below screenshot)

`ROWCOUNT(LOOKUPROWS("Shane_RA", "family_ID", _subscriberkey)) < 15`
