==================
 I have this regex: /^\+[0-9]{8,}/ to check if the answer is a number starting with a +
The strange thing is, this results in an error (Please check your answer):
+43123456789

And this is marked as correct:
+43123456789s

I its is only marked as correct, when I have a + 8 numbers AND any other character that isn't a number or whitespace

No idea why... what did I wrong?
Thanks for your help

 

If you want exactly 8 digits remove the comma in {8,}.
