Your parm at the end needs to be a vector.

Ah, it is weird. I looked at the vex code, and it seems to refer to a variable called vec22 but I don't see where that should be coming from.

As you are using already 4 floats, have you considered using floatToVector4 (/obj/geo/pointvop1/floattohvec1) ?
You could also set the const to produce a vec4. But I guess you have some other VOPs output being floats, right ?

An overview of what's available:

And don't get fooled, as you set it up,it shows no error. but as you go on the error re-appears.

I still confuse about it , If I use FloatToVector4 to output value it works well , but report error when I output value by combine two vector2 to a single vector4 , Why?

I attached a hip file

It looks like a bug to me. Submit it and see what they say.

Got it nailed !!!
Right click on the culprit, and open the Type properties.

in the Parametertab you will find that input 1 is called vecinput 2 is called avecBut then, in the Code tab

$hvec = $vec2;
setcomp($hvec, $avec2.x, 2);
setcomp($hvec, $avec2.y, 3);

The $ is there to create a new instance, at every occurence of this node...

So the parameter interface has different variable names than the script expects.

New Code Should be then

$hvec = $vec;
setcomp($hvec, $avec.x, 2);
setcomp($hvec, $avec.y, 3);

And there we go! It should work as intended

And by the way.... I just noticed....
the vectovec2 has a typo in the parameter label. It reads "Input Vectorr"
