SO Picking Sheet Formula Syntax to display {SO_PickingSheetWrk.QuantityBackOrdered}

SOLVED

Been awhile since I've worked with Crystal and have what should be a simple formula.

The Qty BO Column on the SO Picking Sheet just prints an Underscore.

I'm trying to get it to print the Qty BO if not equal zero and a blank if equal zero.

Keep getting errors when I check it?

If  {SO_PickingSheetWrk.QuantityBackOrdered} <> 0

Then {SO_PickingSheetWrk.QuantityBackOrdered}

Else " "
