identify dynamic objects properties

Hello Robert

I tried recording but it didn't help. Here is the record code.

function Test1()
{
	var panel;
	var textbox;
	Browsers.Item(btChrome).Navigate("https://qa1-payrollplussuite.castandcrew.com/offers/4508/onboarding/profile");
	panel = Aliases.browser.pageQa1PayrollplussuiteCastandcr.form.panel.panel.panel.panel.panel;
	textbox = panel.panel.panel.textboxSocialSecurity;
	textbox.Click(23, 16);
	textbox.SetText("");
	textbox.Click(12, 19);
	textbox.SetText("45");
	textbox.Click(13, 16);
	textbox.SetText("6789");
	textbox = panel.textboxAlternateEmployeeId;
	textbox.Click(36, 12);
	textbox.SetText("1234");
}

I try to stay away from TC name mapping or anything that will limit the code (as much as possible). I use XPat throughout.

The SSN input boxes are designed in such way that as soon as user enters 3 digits in box 1, it shifts focus to box 2. As soon as user enters 2 digits here, it transfers focus to box 3.

I came up with this unintelligent code. 

		var btnSSN1 = page.FindChildByXPath("//input[1][@id='ssn_mask']");
		var btnSSN2 = page.FindChildByXPath("//input[2][@id='ssn_mask']");
		var btnSSN3 = page.FindChildByXPath("//input[3][@id='ssn_mask']");
		btnSSN1.SetText(strOne);				
		Delay(500);
		btnSSN2.SetText(strTwo);				
		Delay(500);
		btnSSN3.SetText(strThree);				
		Delay(500);

But that (semi) solved the SSN issue only. I have all kinds of challenges in this form ( and I have 4 of them.. :) )

For example; I am still baffled why I cannot click a dropdown list box and select an item via automation. I will not stay open for the script to select the option.
