Not letting my variable be a letter
I'm completing a scratch programme that 'draws straws' for a task (allocating a task to someone). At the moment I'm trying not to let the user input letters but I can't find an effective way to do it. Any Ideas?
Thanks

Re: Not letting my variable be a letter
Use the ask button, check its length to make sure it's just one letter using the length of () block. To keep the letter safe, store it in a variable with set variable to (answer).
Does that help?

Re: Not letting my variable be a letter
I think this'll work:
Repeat until answer squared = answer squared
Ask please enter a number
Obviously if it's a number it will work, but I think if there's a letter in it it will ask it again.
