Internet Explorer With Iframes Automation Macro

How to have a macro bring up a website (an internal document website) locate the correct frame uncheck a box, fill in a field with a cell value (from A2) click submit, jump to the next frame within the same website and click a link. my main problem is it looks as though there are nested frames and iframes which im not familiar with. since the website is internal and you wont be able to access it, i have taken snips of the website itself, along with snips of the html and posted them to photobucket. [URL] .......... if you look at the snip of the website the fields i need to be referenced or filled are...

in the frame "frameSearchCriteria" (which i believe is itself within an iframe)
"My Loans Only" box unchecked (html name is "xMyContainers")
"Loan Number" field filled with cell A2 (html name is "xObjectSearchValue")
"Search" button clicked (html ID is "xSearchSubmit")
after these steps have been taken it would then jump to the next frame "frameSearchResults"
and would click the row (html name is "xRowClickAction")

I realize this would be difficult without access to the site, however the posted html and a snip of the website. heres two versions of code i have so far.

Code:
Public Sub IE_Automation()
Dim baseURL As String
Dim IE As InternetExplorer
Dim HTMLDoc As HTMLDocument
Dim mainFrame As HTMLIFrame
[Code] ....

Code:
Sub Xdoc()

Dim oIE As InternetExplorer
Dim HTMLDoc As HTMLDocument
Dim frmCol As FramesCollection
Dim HTMLFrame As HTMLDocument
Dim htmlColl As Object
Dim htmlInput As Object

[Code] ..........
