Restrict values of a choice field based on its current status

[srirao]

Hello Experts,

I am trying to restrict the values of a choice field based on its current value. I understand we can use   "Dependent Field" to restrict the values of based on the values of the other field but what I am trying to do here is little different.

I have a field named "Phase" and it has values viz. Concept, Define, Design, Build, Test, Release, Close.

The default value has been set to Concept. When Phase is set to Concept, it should only show Concept, Define and Close and when it is set to Define it should only show Concept, Define, Build and Close.

I am sure this must have been achieved already by your experts.

Appreciate your help.

Thanks

Thanks Chuck ctomasi

I agree with you that this will dilute the idea of restricting the values in the field but I was trying to figure out how to do this even on change of the field.

Thanks again for your suggestion and I will try it out after I get more familiar with the platform and scripting.
