Auto-populate values if there is only one available selection.

[Rakesh Behera]

Hi All,

There are three choice type field in problem from A,B and C. 

B field values have dependency on A filed value and C filed values have dependency on B field value. 

I want to auto-populate  values if there is only one available selection in filed both the filed B and C.

For example: 

1) Field B populates with value if there is only one option depending on the value in Field A.

2) Field C populates with value if there is only one option depending on the value in Field B.

Thanks.

Hi Mark,

Thanks for the reply. I have tried to achieve this through client script but I think that is not the conventional way as I have to write code for each single value which have only one dependency with another filed.

e.g:-

var  x = g_form.getValue("field A"):

 g_form.setValue("field B", x);

If I am following this way then that would a long script for this solution. Just want to check is there any other conventional way to achieve this requirement.
