Button to add value to table
I have a solution that they want to be able to click a button 1, 2, or 3 and have that value added to the table and then the button highlighted and the other two greyed out. I could figure out how to add the value with a value list, but not sure on approach with the buttons
You can use conditional formatting to turn the button text grey to "grey out" the buttons. In FileMaker 13, you can make them disappear all together.
In either case your script can set values to global variables or fields and the expression in the conditonal format or "hide object when" setup can refer to that variable in order to control the appearance (or visibility) of the button.
