Picklist has three choices, the last one of which is "Other".  If "Other" is chosen, open the next field to enter data.  So the text field is invisible unless "other" is chosen in the picklist, at which time it appears and user sees instructions to enter the "Other" data.

I have a link on the home page but instead of in the sidebar on the left side of the screen I created a tab at the top of the page for the link.  The link leads to a folder on the company shared drive.  It used to work fine but has stopped working on the tab.  While I am in the editing box and click on Preview it works, but it won't work on the tab at the top of the page.  Can you help me figure out how to make it work on the tab?

Thanks so much.
