For some reason I am having trouble getting this code from the tutorial in the Demo version of DP.
Running it brings this error.

Could not determine parameter type of "levels-y" at line 24

I cannot see why this is not working. I have copied it from the tutorial and cannot see an obvious reason why it doesn't like levels-y. Does this work on anyone elses machine? This is probably something stupid I'm missing, but I'm stuck unless I rewrite the object stack a different way. I was just wondering why it doesn't work, when it is the example code.

You have included some strange formatting when you copied the code from the demo

Isn't that exactly the same code as I posted?

I don't believe the text of the code is the problem. When I copied your code directly to the DB Pro editor I received the same error that you did.
When I copied to "MS Word" the copied that to DB Pro I get the message cannot load image...

I cannot explain why but suspect that the tutorials have some type of hidden imbedded format that the editor has problems with.

Hope that help

Any text using - might be a problem if you copy direct from the help file. You can always load the projects directly from the tutorials folder.

Ah, I tried loading it into Notepad but still seemed to have the same error in. Received the full version today so it may have the code in. Guess I'll just have to type it all out manually if not.
