Is there a way to check if a string has a number in it and if so to return it?

You are able to use string patterns to isolate numbers from a string. The %d character class represents any digit, and adding the + represents that you want to retrieve any number of digits next to each other, so you can use string.match with this info to retrieve numbers from the string:
local function GetNumbers(String)
return string.match(String,"%d+")
end
print(GetNumbers("banana 63 banana")) --> 63

I don't think you understand. I don't know what the number will be before hand.
I didn't know what you meant by return, go to the script where the number is being generated in the first place and print it
I cannot do that. It is being generated by a user.
