List Box - Always one selected value

[#1]

Hi,

I have created a hierarchy using a list box, because of which the option ALWAYS ONE SELECTED VALUES is diabled, wih which user is able to select more than one value in the hierachy. Is there any way to restrict the user to select to only value.

=[OpPrc L1] &'/'& [OpPrc L2] &'/'& [OpPrc L3]

Kindly Advice.

Regrads,

You must select a single value in your list box first before you can enable 'always one selected value'.

See this thread for more details.    Always one selected value how to enabled?
