Am I even close on how to do this? I’ve googled alot and still can;t  
get this to work

**Monday** \<%= f.check\_box :monday %\> \<%= observe\_field(:monday\_checked, :function =\> visual\_effect('appear', 'monday-div')) %\> \<%= observe\_field(:monday\_unchecked, :function =\> visual\_effect('fade', 'monday-div')) %\>

**Start**  
 \<%= f.time\_select :monday\_start, :twelve\_hour =\> true %\>

**End**  
 \<%= f.time\_select :monday\_end, :twelve\_hour =\> true %\>
