When we try to use the lookup tab, then the find tab in wo-a, it asks if we wish to see open only-y; with the options of y or n.  If we say yes, we get a fatal error that states: "The field you are trying to use is unallocated.  It may belong to a file that hasn't opened yet, or was an array removed from memory." "temp00"
(Note the " are small boxes that I am unable to type.)
 
If we say no to the above question, it seems to run fine-but we must scroll through all work orders, which is time consuming.
 
Anyone have any idea what is happening here??
