Hello,
I'm using the survey flow logic and I want to branch people to select questions if they've input any type of non numeric string into a form field response.
It appears the only way to do this is by checking whether their input matches the regex code for any non numeric string.
E.g. if they enter
1
100
1000000
They would not match the regex.
If they enter
$100
One hundred
$1k
They would match the regex.
I've tried just about every variation of strings, non numeric, character match regex and none of them seem to accomplish this. Is there any suggestion for a regex to do this?
The survey flow logic states that

"If question # matches regex ^[]$"
