Security Connection - Security Checkpoint Connection Missing

[Mario]

Hey!
I’ve been playing Airport CEO for almost 6 hours, but I’ve never figured out how the Security Connection works in stands. I saw a few discussions here in the forums, but they didn’t help me unfortunately.
The airport: (it’s not the final airport )

In every stand I get: “Security Connection - Security Checkpoint Connection Missing”
Any help is appreciated!
Thanks!

Hello! You have a section of open zone between your two secure zones. This causes your stand and security check-points not to connect. You need to build sidewalk and zone that area as secure to make sure they connect.

Also the section before the control post should be unsecure.

Ohh, didn’t notice that. Thanks!

[Mario]

Thanks

Where can I find the “sidewall”?

[Jas]

Infrastructure and transport. Click on the 5th icon with the person

Sidewalk btw

[Mario]

Ohh, sidewalk, okay

EDIT: I’m getting: Structure Position Not Valid

[Jas]

Correct floor?

[Jas]

Also screenshots will help

[Mario]

It was trying to build the sidewalk on a service road That was the issue

[Jas]

It’s all a learning curve

[Mario]

Hmm…I’m still getting the same issue:

[Jas]

The door is not secure zoned , plus your exits are facing a wall

[Mario]

@Jas

The door is not secure zoned

Thank you so much! It’s working now!

[Jas]

You need to fix your exit door.

One side secure

Other side unsecure zoned

[Mario]

Yup
Thanks!
