Public member 'z' on type 'Double' not found

hello, I'm beginning with Vb script and have one question - probably very easy:
I found it in one book (as a part of GH def)

If s1.z = s2.z And s1.z = e1.z And s1.z = e2.z Then
s1_ = s1
e1_ = e1
s2_ = s2
e2_ = e2
End If

output message says: " 0. error: Public member 'z' on type 'Double' not found. (line: 0)"

I named all inputs and outputs as it is in the script.
greets

It looks like the script is meant to be used on Vectors or Points (or maybe even Planes). These types all have a Z property. Doubles (i.e. floating point numbers) do not. You're either feeding the wrong type of data into this script or maybe you've assigned the wrong kind of type-hint?

Thanks ! Right, I was connecting numbers and not points but i guess most confusing part is that the component is turning red even when nothing is connected.(I used Gh 8.xxx)

cheers

It turns red because there's a compiler error (i.e. Public member 'z' on type 'Double' not found.). It's a bit odd that it supposedly happens on line 0.

What are your input parameter type-hints? Are they set to Double or Object or Point?

Yes, now when I changed input parameter type-hints from object to 3d point, Vb component turned gray.

Thanks again !
