How to create a regular expression in Google Forms that checks for character length and capitalization
<p>I am trying to create a regular expression in Google Forms for a quiz for middle-schoolers. I would like for the quiz to display an error code if students do not include any capital letters in their response. I would also like for the form to enforce a minimum character limit (250). I have tried using: </p>

<pre><code>/^.{250,}$/
</code></pre>

<p>But Google Forms throws an error and reverts to previous version of the form whenever I put in curly braces. Here's what I have so far to check for capitalization:</p>

<pre><code>[A-Z]*[.]\s[A-Z]
</code></pre>

<p>How do I add onto this to get it to also check for character length? As you can probably tell, I'm a novice. A teacher, not a programmer. I'd appreciate your help. </p>
