Getting numeric input from user on screen

[shylock]

Okay, hopefully I can make this clear.

I have a hero who trades goods. So I have a bunch of prices for different goods in different towns which move randomly and also in response to certain events in the story. That's easy. I want hero to be able to buy/sell in different towns. So I need to have a screen that pops up on demand and displays the relevant prices in question, allows hero to input desired quantities to sell/buy, and checks it against hero's money balance.

I really have no idea how to do anything visual. I've been reading a lot of the documentation for ui functions - ui.grid, ui.button, etc - but it just doesn't make any sense for me right now. Any advice is really appreciated.

Actually I would like to have that in my project as well, though it must be some sort of naming your pets/items/characters. I saw an example in the latest Ren'Py tutorial, but it did not reveal the tag it used to make such. Let's hope someone could help.

ui.input takes input from the player. There's an example on the page there. You can look at the source code for the tutorial, too (hitting Shift+E should take you to the general area.)

Oh, yeah. The codes can't be shown if you open the files by itself, so it should be opened using the Ren'Py Launcher (Edit Script, then all the files used in the tutorial will be shown.). o.o Thanks.
