WaitOnDialog only returns -1

[kemmererm]

I created 2 custom Dialogs and used nearly identical code for both of them but for some reason only the first one i created works. WaitOnDialog for the second one only returns -1.

First I had a problem because they were both created with a resource identifier of 0, I changed the second dialog to have a a resource identifier of 1.

Here is the code I use to create the dialog:

function NUMBER RemoteSiteDlg()    
STRING szDlgName;
BOOL bDone;
NUMBER nCtrl;
begin            
                 
	szDlgName = "RemoteSiteDlg"; 
	bDone = FALSE;
	
	nCtrl = EzDefineDialog(szDlgName, ISUSER, szDlgName, 0);
	
	if (nCtrl = DLG_ERR_ALREADY_EXISTS) then
		MessageBox("Dialog already exists", SEVERE);
		abort;
	elseif (nCtrl = DLG_ERR) then
		MessageBox("Unspecified error", SEVERE);
		abort;
	endif;
	
	while (!bDone)
		
		nCtrl = WaitOnDialog(szDlgName);
		
		switch(nCtrl)
			
			case DLG_INIT:    

			case DLG_ERR:
    			MessageBox("WaitOnDialog Error DLG_ERR", SEVERE);
    			abort;
    		
			case NEXT:
				bDone = TRUE;
				
			case BACK:
				bDone = TRUE;
			
			case CANCEL:
				Do(EXIT);
			
		endswitch;		
		
	endwhile;	 
	
	EndDialog(szDlgName);
	ReleaseDialog(szDlgName);
	
	return nCtrl;

end;

I checked and triple checked to make sure that the value in szDlgName is the actual name of the Dialog as it appears on the dialog pane. Is there a way to get a more descriptive error message out of the install shield interface?

This issue appears to be that resource identifier needs to be 0 and that i misdiagnosed the earlier problem that caused me to change it to 1. What does the resource identifier do?
