How to check if there are numbers in a variable?

[cesario678]

I have a table, and from this table, I put the data into a variable. Some rows have numbers, others don't. I would like to read this variable and, if it has any numbers, that's okay, and if it doesn't have any numbers, it gives an error. Can someone help me?

Regex cube with \d (means any number in regex)
make sure to check 'error when the answer is empty

Will result in good exit if it has any number
and bad exit if it does not have a number
