I am almost positive that this is correct but it keeps telling me parse error. could someone help please.

Also could you mention what a parse error is. Thank you!

script.js 
for (var count = 3, count <= 157, count +=1){
  console.log(count);
}

Hi Robert,

Instead of comma's separating the values in the for loop, you need to change them to semi-colon. Other than that works perfect.

Take care and Happy Coding!

Hi there -

The parse error means there was a problem in parsing (or reading) your code - it indicates a syntax error somewhere. Yours was tough to spot, but it lies in the start of your loop - instead of commas, there should be semicolons separating the parts of the 'for' loop declaration.

Aside from that, it wants the numbers to start from 4, so the count variable should start there too. It also wants you to stop after 156, so the second part of the loop declaration should be either "<= 156" or "< 157".

Hope this helps!

I changed the commas to semicolons and it still doesn't work. I still get parse error :/ I think it might've made it worse even.

Did you manage to get it? I just tried one more time, just changing the commas to semicolons and changing the numbers, and it worked. This was the code:

for (var count = 4; count <= 156; count +=1){
  console.log(count);
}

If it doesn't work, would you mind posting the code you're using? That way, we can figure out what's going on.

Change the "," in the for loop to ";" and start at 4 not 3 also you want to count to 156 not 157^^

I tried it and passed 

for (var count = 4; count <= 156; count++){
  console.log(count);
}
