Validation for Captcha

I have the attached page boat-insertShowIf.php
with three "Validation Show if's"
the page is working OK.

I insert Captcha object (and with F12) check the page is still working OK,
and find the page is working correctly.

I then ‌insert the message "The entry is incorrect. Please try again ".
I highlight this message (and with F12) check the page is working OK,
I find the page is still working correctly.

I now highlight the validation message under the Captcha object

Open WA >Forms >Validation >Server Validation
The Server Valdation: Insert box opens
Validation trigger: any form post Entered
Validation Type: Like Entry Entered
Sever Variable: session captch_Security_Code_1

Next Plus icon click
Same as Lightning bolt FormPost:Insert_Basic_Default
Security_Code_1

Code inserted <?php echo((isset($_POST["Security_Code_1"]))?$_POST["Security_Code_1"]:"") ?>

Failed redirect: entered the same page

I attach an image to show the steps for the like validation

After the Server Validation is applied to the Captcha none of the validations on the page are working.

I saved the non working page as boat-insertShowIf with capture.php
and the working page as boat-insertShowIf.php
Can you see where I am going wrong please?
Many thanks
John

You added a second server validations server behavior to the page instead of adding the CAPTCHA validation to the first one. You should edit the existing server validations and add the CAPTCHA validation their and remove the first Server Validations server behavior. You should only have one Server Validations server behavior applied per form.

Thanks Ray
I dont quite understand what is being said.

I have had a look at the code and I cannot see where there are 2 Server validations.

What is the "CAPTCHA validation"

I notice now that data from the selection box is not being placed in the database. I am almost sure it was working last night.
Later:
The selection box does not seem to work at all.
I have tried it dynamic and as a straight list but is is not entering the database field.

I've attached a screen grab of the Server Behaviors panel when I open your page in Dreamweaver.

You can see that the first and fourth item listed are both "WA Server Validations"

That means you added it twice. You should have edited the existing one to add another validated field (CAPTCHA) where the other three validations are instead of adding a new Validation server behavior.

Now you can delete the first one and edit the second one listed to add the captcha there instead.
