Getting Input from the Smartdashboard

[Merfoo]

Hello, so I'm trying to get input from smartdashboard using the built in getNumber function. However when trying to get the data it doesn't seem to get the update data. For example I'll have a box and when I enter in a new data it still gets the original data. I know if you press enter it'll update it, but it'll also disable the robot since the emergency disable button. I've tried just putting the mouse in another box but that doesn't work. Does anyone have a solution to the problem? Sorry if its long.
