help with formula

BH

Hi,

Suppose, I have a Tenant table and Units table. Tenants table has a column called UnitID, which is linked to Units table(column ID). I've created a formula to check if there are any tenants associated with that unit.  If the condition is true, the results should be 1. If the condition is false, the result should be 2. I'm using the formula below, with no luck. The record only appears if the condition is true. However, if the condition is faulse the record is skipped, even though I'm not using a any filters. What am I doing wrong?

if {Tenant.UnitID} = {Units.ID} then 1 else 2;
