Using the FileMaker Script Debugger and Data Viewer

Beginner

The Script Debugger and Data Viewer are FileMaker Pro's built-in debugging tools. Learn how to step through scripts, set breakpoints, and inspect variables and field values in real time.

What you'll learn

How to open the Script Debugger and step through a script
How to set a breakpoint so a script pauses at a specific step
How to use the Data Viewer to inspect variables and evaluate expressions

The Script Debugger lets you execute a script one step at a time while the Data Viewer shows the current value of any variable, field, or calculation expression — together they are your primary debugging environment.

Stuck is a valid status

Open the Script Debugger and run a script

Enable the Script Debugger from the Tools menu in FileMaker Pro. Trigger the script normally and it will pause at the first step, waiting for you to step through.
