Here is the html box I am trying to click onto,

```
<div style="min-height: 100px;" class="fr-element fr-view" dir="ltr" 
    aria-disabled="false" spellcheck="true"
    contenteditable="true">
    <p><br></p>
</div>
Then trying to reply with this button

<button type="submit" class="button--primary button button--icon button--icon--reply">
    <span class="button-text">
        Post reply
    </span>
</button>

```

Here is what I have tried 

```
WebElement Post;
Post = driver.findElement(By.xpath("//input[contains(@class,'fr-element fr-view']"));
Post.click();
Post.sendKeys("okay");

driver.findElement(By.xpath("//button//span[text()='Post reply']")).click();

```
