# [Regex] Specify Upper and Lower Number of Matches - I believe my solution should work, why is it not?

Regex has been easy, and it still is, but I do not understand why my solution wouldn’t work here. One of the parameters you must pass is `Your regex should not match "Ohhhhhhh no"` and this is the one parameter my solution would not work with, meaning that `/h{3,6}/` was matching the test with 7 of the letter h.

My Solution:

``````let ohStr = "Ohhh no";
let ohRegex = /h{3,6}/; // Change this line
let result = ohRegex.test(ohStr);
``````

Working Solution From the Hints:

``````let ohStr = "Ohhh no";
let ohRegex = /Oh{3,6}\sno/; // Change this line
let result = ohRegex.test(ohStr);
``````

Why would this challenge only pass when you actually search `/Oh{3,6}\sno`? Is it something to do with how FCC’s IDE works? Please keep in mind that my solution did pass every parameter except the last one which I outlined above.

the test is good. The reason your regex does not match the last test is because what your saying when you write `/Oh{3,6}/` is match me anything that has upper case O and between 3-6 characters of the letter h, and if you look at the last case
`Ohhhhhhh no` you are indeed matching between 3-6 of the letter h’s but this isnt what it wants. if you look at the correct regex that the test requires to pass `/Oh{3,6}\sno/` this says… only return me a match that has between 3-6 letter h’s plus a space, which is denoted by `/s` followed by a character ‘n’ followed by a character ‘o’ and if you look at the examples does the last test example match this case? Do you see what I mean now?

Edit: basically the problem with what you wrote is that while it does indeed match things with a capital O followed by between 3-6 of the letter h, but it takes no account for any additional characters that may or may not come afterwards. hope this helps.

THAT makes SO much more sense now. I didn’t think of the point that we need to limit the number of h’s so it doesn’t continue to search, thank you!
