Issue on select a picklist in a subform

Hello,

I have a form with a subform. In both of them y have a dropdown. I need to select an option by code.

For example:

In form I have the Dropdown whith values a,b,c. on add, on load I use the code Dropdown.select("a"); to select the value "a" . It works.

In subform I have the Dropdown whith values d,e,f. On subform, on Add Row the code row.Dropdown.select("d"); to select to select the value "d". Id does not work. Zoho creator say:

Error at line number : 1
'
Dropdown' does not exist in this form

The field exists and I can use in in code like clear row.
Dropdown;
