ScriptFire for FileMaker
To update your version of ScriptFire just download the latest version. If you have registered the plug-in you can simply replace the copy on your system by the updated version (this will not break your registration).
Which Version Do I Use?
To find out the exact version of ScriptFire you are using check the result returned by the plug-in function SFire_Version. You can also get this information from the file version info. On Mac locate the plug-in file in the Finder and hit Cmd+I. On Windows locate the plug-in file in the Explorer, right-click it and choose Properties. You will find the version information on the Version tab.
