Getting data from webpage using "classnames" that are the same

I cannot seem to retrieve data using "getelementbyID"
Ex: MainBal=ie.document.getelementbyID("cashAvailBal1").value

However, thanks to one of your posts, this works.
Ex: MainBal=ie.document.getelementsbyClassname("amount") (0).innertext

Problem?

The next amount I want to retrieve has the same classname. "amount"

I tried this: ie.document.getelementbyid("cashAvailBal1").getelemensbyclassname("amount").value

Did not work.

Code Example Start:
Dim MainBal As String, BudgetBal As String
Do While IE.Busy
Application.WAIT DateAdd("s", 1, Now)
Loop
'This works just fine
MainBal = IE.document.getElementsByClassName("amount")(0).innerText

Do While IE.Busy
Application.WAIT DateAdd("s", 1, Now)
Loop

'This does not
BudgetBal = IE.document.getElementsByClassName("amount")(1).innerText

MsgBox MainBal & vbLf & BudgetBal
Code Example End

Any help with this would be greatly appreciated.

BTW this is my first post

Problem solved. By accident. The second set of () indicates the field that is to be accessed.
But still cannot run the macro without the error messages before each attempt to either input data or retrieve data.
Macro is successful, but requires a restart after error messages.
