Trying to acSubtract in VBA for AutoCAD

[cashimplosion]

Hi everybody. I'm new here.

Here's my problem. I have a While loop that draws a cylinder over and over again at user-specified coordinates, and I want each occurence of the cylinder to subtract from a large box that is also on the screen.

This is where my problem is.

I've tried experimenting and using code that I've found around the internet, but VBA always prompts me for more info, like so:
piece.Boolean(acSubtraction, tool) =

It prompts me for another set of complete info after the equals sign. I have a VBA book but it leaves out lots of VBA options, such as the Boolean operations.

Anybody know anything about this?

Actually, I just figured it out

If I forego the perenthesis, it works perfect.
Hmm..
