How do I make a textbox accept only numbers?

This may have been asked before but I haven’t found one that works. I want the player to be able to put a number from 0-99 in a textbox and not be able to use letters or symbols.

Set Type=numbers in TextBox properties.

To limit the number of characters to 2:

TextBox On Text Changed -> TextBox Set text to left(self.Text, 2)

Also, see Tutorials section, there are lots of helpful examples on how to customize texboxes:
