Is there a way to set a condition such that something will happen if any text is entered in a field, and something else if it is empty? This would be useful with simulating required fields: if the text box is empty and the user advances, an error shows up. If the use entered something, they can advance.

I would assume you could set up a conditional or switch branch: Is condition “[TextBox_value] == %ANY%” satisfied?

However, this cannot be done since the value needs to be specific (a string, index, etc from somewhere else in the prototype).

A simplified approach may be to use the empty string “”, like this:

Is condition “[TextBox_value] == ”” satisfied?

This approach is used in the Fwitter example plot.
