Show/Hide Fields

Show/Hide Fields

Hi,

I'm trying to show/hide fields based on the status of a dropdown. I've created a test form with the following fields....

Dropdown
            Items 1
            Items 2
            Items 3

Field 1a
Field 1b
Field 1c
Field 2a
Field 2b
Field 2c
Field 3a
Field 3b
Field 3c

I'm trying to use a workflow to only show fields 1a,b,c when Items 1 is selected, fields 2a,b,c when items 2 is selected and fields 3a,b,c when items 3 is selected but I can't seem to get it to work.

Ideally I will be using this to have all relevant data for the record in the same record and show certain details depending on which view is selected in the dropdown.

Any ideas? I'm using IF to determine the status of the dropdown then hide to hide the unwanted fields but being a complete novice I keep getting errors.
