Conditional Formatting Show Field

Hello,

So I am trying to show a field depending on a selection from a separate field.

So I have a field called Time Limit Options : Choice Field | Selections are: No Time Limit, Time Limit

Then once the user selects Time Limit I need a field called "Time Limit/Days" to appear.

So Using the conditional formatting, I created a Custom New Form, then selected the <tr> tag that held the "Time Limit/Days".

Then I selected Create>Show Content>Advance

Then my expression was @Time_x0020_Limit_x0020_Options = 'Time Limit'

I hit ok and save it.

Then When I go to the new form, It says "An unexpected error has occurred."

It works fine with no formatting, but I would like to get this to work.

Thanks

Brandon
