I've got a multi-form program and I am having a problem with adding a
new form to the mix.

I have a main form with buttons on it to call the various forms.  I use
the following code under the click method for each button to call each:

Form1.Showmodal;

But, when I went to create a new form, I did the same thing as above.
I also added the name of the new source to the uses of the main source.

When I compile the program I get the message EREADERROR, invalid
property value in the button click.  I am obviously missing something,
but I have yet to figure it out.  Any help would be much appreciated.

Thanks,

Well the fact that you are trying to create and view two modal forms at
the same time is a problem.  Modal indicates that you want a form to be
on top - Permanently or at least until proper attention has been given to
that form (i.e. a modal dialog to retry, abort, or cancel will not let
you access any other form or function until a response has been given
to the dialog).  When you say you are trying to run a multi-form app,
I'm not sure if you mean as MDI Parent/Child, but I don't think that MDI
child forms can be modal, anyway, so if you are trying to
MDIChildForm.ShowModal, that would almost certainly generate and
error/exception or at best ignore the request.  MDI or otherwise, trying
to use to modal forms at the same time will cause problems.

Hope that answers your question.
