Problem with Editing Text Boxes
I an trying to put values in a text box, so that the text will display the length of segment a and not the letter a. I know how to do this, When editing the text box, you click on the Geogebra tab and double-click on the object that you want to appear. A box appears in the text with the variable in it, which can then be edited. I have been able to do this before using the online app. I have done this with other files, but it is now not working. I can't even double-click; It's like it's text and not something clickable. So I can't finish the activity that I'm working on. Please see my file "Law of Sines_in progress" at https://www.geogebra.org/ge...
Thanks for any help you can give.
