reCAPTCHA not showing up in the contact form pop-up

Hi,
I am having difficultly in getting reCAPTCHA to show up in my contact form. The keys are all in place in the integration section. I am not sure what else I am missing here. If I press submit after entering al lthe required details, and since I can’t see the reCAPTCHA, I couldn’t submit without an error. Please help.
The contact form I am using has coded to as follow:

<label> Your Name (required)
[text* your-name] </label>

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

<label> Subject (required)
[text* your-subject] </label>

<label> Your Inquiry (required)
[textarea* your-message] </label>

[recaptcha size:compact]
[submit “Send”]

Thanks.
