Before you can automate JMP, you must establish a reference to it. If you are using Excel and have the "Developer" menu enabled, you need to go to Tools->References. Within the dialog that comes up, you can select "JMP". The pane below the selection list should have the Location: C:\Program Files\SAS\JMPPRO\11\jmp.tlb. Once you do this, then you can start JMP up in VBA code. If you have already done this, make sure the path to your Big Class file is correct. For instance, if you are using JMPPro, it will be c:\program files\sas\jmppro\11\samples\data. Note the JMPPRO in the directory, not JMP (and a real version #).
