reCAPTCHA wasn't entered correctly

On my contact page I have a plugin called googleDirections - To Here. Basically it puts a small google map where ever you enter the code. It also puts a text box. A person types in their address and clicks on the button. Then it displays the directions next to the map.

I'm using reCaptcha which works fine. However, I've noticed an issue that only happens in Firefox. When someone types in an address in the textbox and clicks the button to get directions at the top of the page is the following error:

The reCAPTCHA wasn't entered correctly. Go back and try it again
( reCAPTCHA said: incorrect-captcha-sol )

I've checked and I don't have the image verification feature enabled in ChronoForms. I only have the ReCaptcha plugin enabled. What I don't understand is why is this message coming up? The textbox is part of the googleDirections plugin which has nothing to do with ChronoForms. Granted, the plugin code is inside of a form handled by ChronoForms. I had actually posted yesterday about getting it to work and was told to enable mambots in ChronoForms, which worked.

Is it because there's a form within a form? This is an example of the plugin code that I have in the form:

{googleDir_tohere width=400 height=360
home_label="Google Inc.~1600 Amphitheatre Parkway~Mountain View, CA 94043",
home_lat=37.4219720, home_long=-122.0841430}

Edit:

I wanted to add that if I use just the default image verification that's built in to the Anti-Spam feature of ChronoForms that it does not appear to conflict with the googleDirections plugin.

Hi krackerjax ,

A bit hard to tell without seeing the form but nested form tags are definitely not permitted in HTML and will often cause problems.
