Problem with Surface Division... (Beginner)

Hey guys,

im completely new in grasshopper, but i want to learn it as good as possible.

Now I'm having a beginner-problem. I want to divide a simple surface into four corner points. Please take a look at my parameter structure. Im getting only two indexes, so that i can't choose each cornerpoint. I just can choose the points on the upper edge, or on the lower edge... Can you tell me, how i generate four indexes, so that i can choose every cornerpoint separately?

Thank you so much and please excuse my english ;)

This is a simple example of a couple ways you could grab the corners of a surface. If you just want the corners, you don't need to subdivide the surface. Is this what you are looking for?

the ghx file above contains the components. There are a number of ways to do what you want, the examples above are just a few ways. They are as follows:

Box Corners: Surface->Analysis->Box Corners
Brep Wire Frame: Surface->Analysis->Brep Wireframe

Not shown, but probably the most efficient component would be:
Brep Components: Surface->analysis->Brep Components

(btw, notice the trend here? all the components to "analyze" a surface are under the Surface->Analysis tab!)

Thank you so much! I did all the time divide surface... I got 4 points with this, but just 0 and 1 as indexes... You helped me so much! Thank you!
