You don't a find layout, but you do need a script. You also need to clarify whether the find against these multiple criteria uses "and" logic or "or" logic.
From the example values, I will assume that you want to find, for example, all records with a status of "pending" or "dropped", not "pending" and "dropped" as that makes no sense given these values.
Set up your drop down list on a text field with global storage. (I'd use a check box field rather than a drop down as I think this is better inteface design for a value list that permits multiple value selections, but the same script will do the job either way here.)
Use this script:
Enter find mode //clear the pause check box
Set variable [$I ; $I + 1]
Exit Loop If [$I > valueCount ( Yourtable::globalStatusvaluelistField ) ]
Set Field [YourTable::YourStatusField ; getvalue ( Yourtable::globalStatusvaluelistField ; $I ) ]
If [$I < valueCount ( Yourtable::globalStatusvaluelistField ) ]
Set Error capture [on]
This creates separate find requests (the new record/request step does this) for each value selected in the value list so that any records with a status of any one of the selected values is found.
Thank you so much. I have no experience with scripts, so I'll give it a try.
