Frustrated. Here's what the manual claims:
The text you type directly in the Edit field is considered as static, i.e. it's not affected by the objects modifications. If you need to create a dynamic text, which displays the changing values of an object, select the related object from the Objects drop-down list (GeoGebra Desktop Version) or the tab in the Advanced menu (GeoGebra Web and Tablet Apps). The corresponding name is shown, enclosed in a grey box, in the Edit field. In the GeoGebra Desktop Version, right-clicking on the grey box allows you to select, if "Definition" or "Value" of the dynamic object is displayed.
Well, I opened a text box. I got the 'advanced' menu. I get a list of objects. But I cannot select any object. I can't right- or left-click. The text box is totally frozen and unresponsive. I can click on the list to the left of objects, but then this does not seem to communicate with the text box I've opened.
ALL I want to do is show the results of a computation in the text box, and how that result changes as I move a certain point. It should be easy. Instead, it's frustrating.
Can anyone help? I'm using Geogebra Classic. I don't
