Is it possible to display the custom field values based on other two custom field values ?

[Maheshbatta]

For example, I have custom filed A with values 1,2,3 

                                custom field B with values 4,5,6 

                                custom filed c with values x,y,z, !,@,#. 11,13,15

If I select custom filed value A as 1 and custom field value of B as 4 then custom field C should display following values x,y,z

I'm using script runner plugin, with following behavior, but no luck

import groovy.transform.BaseScript
import com.atlassian.jira.issue.customfields.option.Option
import com.onresolve.jira.groovy.user.FormField
import com.atlassian.jira.component.ComponentAccessor
def A=getFieldByName("A")
def B=getFieldByName("B")
def C=getFieldByName("C")

if(A.getValue() == "1" && B.getValue().equals("4")
{

C.setFormValue(optionFor(C, "x", "y", "z").optionId)

}

else if(A.getValue() == "2" && B.getValue().equals("5")
{
C.setFormValue(optionFor(C, "!", "@", "#").optionId)
}

@Maheshbatta  , Shouldnt you be using formField.setFieldOptions(Iterable) instead of setFormValue on C?
