Hi Nick,

Use:
Code:

---

{Units sold Period n}<>0

---

where {Units Sold Period n} is one of:
Code:

---

{Units Sold Period 1}
{Units Sold Period 2} 
{Units Sold Period 3} 
{Units Sold Period 4} 
{Units Sold Period 5} 
{Units Sold Period 6} 
{Units Sold Period 7} 
{Units Sold Period 8} 
{Units Sold Period 9} 
{Units Sold Period 10} 
{Units Sold Period 11} 
{Units Sold Period 12} 
{Units Sold Period 13} 
{Units Sold YTD} 
{Units Sold LY}

---

from the Inventory Item Master table. There's also and {Amt Sold Period n} field you could use instead. If you want to scan several periods, then add the individual periods together and see if they sum together, like this:
Code:

---

({Units sold Period 1}+ {Units sold Period 2} + {Units sold Period 3})<>0

---

OK?
