captcha not working

when i drag the contact form 7 widget into my sidebar I get this code

[contact-form 1 "Contact form 1"]

however when editing the form with the captcha code i get this to place into my widget

[contact-form-7 id=”4388″ title=”contact”]

here is the form code
<p>Your Name (required)
[text* your-name] </p>

<p>Your Email (required)
[email* your-email] </p>

<p>Subject
[text your-subject] </p>

<p>Your Message
[textarea your-message] </p>

<p [captchac captcha-871] </p>
<label>Enter the code: [captchar captcha-871] </label> </p>

<p>[submit “Send”]</p>

my provide says all requirements are met including the temp folder being writable. The form shows properly but no captcha

I have substituted [contact-form-7 id=”4388″ title=”contact”] for the [contact-form 1 "Contact form 1"] in my widget but still no captcha
