I'm not sure what your level is, or what the problem is, so I'll begin at
the basics.
To pass values (of any type) to another VI, you have to connect the
indicators to the connector pane. Right click the vi icon in the top right,
and select Show Connector. You should always select the 4X4X4 connector
pane, with the Patterns option (again, right click the icon). In 8.5 this is
the default (I think since 8.0, but I'm not sure). Then, click any of the
little squares in the connector pane (the icon, but now it shows the grid),
and then one of the indicators on the front panel. Now, the VI has an
output. You can do the same with the second VI, only now select a control.
This becomes a new input of the VI. In a main VI, you can now connect the
two, if the two data types are the same.
One problem with your senario is that the user selects settings in a
control. To be able to pass the control values to another VI, you'll have to
create an indicator of each control you want to pass. Then connect the new
indicators to the connector pane, and you can pass the control values to the
next VI.
Another problem is that you might have several (related) values. You can
bundle them in a bundle or cluster, to save connectors. You'll find that it
pays off to make a strickt type def of those clusters, so you can change
them all at once.
Hope it help, just let us know where it goes wrong.
