7. Type >0 (this time no quotes are required) in the Criteria list box and then click
Add .
Your search is entered at the top of the dialog box, in the Action box. (You wouldn't

8. Click OK until you're back in the Edit Script window .
The Perform Find script step now has options set ( Figure 11-9 ). Notice that the Edit
Script window has an * (or asterisk) at the end of its name. That tells you you've
made changes to the script that haven't been saved. Whenever you close an Edit
Script window that has an asterisk, FileMaker asks if you want to save changes to
your script.
Figure 11-9. Your finished script should look like this. It wasn't too hard to improve, and
it's very easy to understand. The * at the end of the window's name tells you that the
script's changes haven't been saved.
9. Close the Edit Script window and then, in the dialog box that follows, click Save .
Or choose Scripts→Save Script, or press Ctrl+S (Windows) or ⌘ -S (Mac). Either
way, the Edit Script window stays open, but the script is saved. You can use this com-
mand to save a script midstream while you're working on it.
