Rebuild a mathematical dart training game

Hey all.

I just trained myself a bit in the APP Inventor. I want to rebuild a training game for darts - you can see a picture here:

There you have a numberpad, where you can enter numbers between 0 and 180. Can anyone explain me how to build a functionall number pad? I already build the UI with a table and buttons in it. Also a textbox for the result.

But when I go into the blocks, its only possible to generate numbers between 0 and 9. How is it possbile to insert more then one digit.


Please post a screenshot of the blocks . Where exactly you need to insert more than one digit ?


9 scores are not possible. 163, 166, 169, 172, 173, 175, 176, 178 and 179, and don't forget about 0, missing with all three darts :wink:

This is the block:


And for example if you thow 100 points, you need to insert 1, 0 and 0 for the 100, then click enter.

See an example

Thank you so much <3

Well I guess its to hard for me.
For example since you mentioned two labels in your screenshot, but I got only one label.
