hide command not hiding fields

Hi,

I have a form named stage with the following field and data:

-Stage

-Grapes

-Fermenting

-Juice

-Must

I have another form named Analysis that contains fields that I would like to hide in function of the stage chosen. For example, if the user chooses "Grapes", I would like to hide all fields except Brix and pH. To test my syntax, I have only been trying to hide the "Lot" field. I have used the following to try to accomplish this:

if(input.Stage.toString() == "Grapes")

{

hide Lot;

disable Lot;

}

I am not getting an error but the field "Lot" is not being hidden.

I would be grateful for your assistance.

Best regards,

Jeff
