Spinner control, updating another field

[kingja]

     I have a multi-page form and on page 1 is a height field (cli:height).  I have added two spinner contols, using two local variables, loc:feet and loc:inches.  In the validate embed of cli:height, I have code to calculate the total number of inches and place this result into the cli:height field.  This works as expected upon saving the form.
     However, I want the user to be able to use the spinner controls and immediately update the cli:height field with the total inches.  I have tried numerous embeds but have not had any success.  Any suggestions?

Thanks,
