But you can indeed edit data in FileMaker GO. You just can't modify the design of the database.
FileMaker Pro does not offer any support for touch sensitive input. You may find that such is possible with a plug in.
But please note that if you tap a container field in FileMaker GO a menu will pop up where both the camera and a signature are offered as input options. This requires no more design work in FileMaker pro than placing the container field on a layout.
Thanks for the quick response! I still can't seem to get it to work, but here are the steps I took. (Sorry I'm a bit new to filemaker)
1. Went to the iPad layout in filemaker Pro.
2. Inserted a field and created a new one called signature and made the type a container.
3. Added the container to the layout.
4. Went to the layout on the iPad and tapped on it and nothing happens.
