How to save the settings using Save button

[Nancy12]

Hello All,

I am new to AutoIT. I am trying to modify the Skype video settings and save the change.
The settings works fine but i am unable to save it.
How do I on click on  the "Save"Button.

I tried this using Control Click and specified the Classname, text, instance etc. but this did not work for me. 
The instance Id keeps changing to either 3 or 7 every time I tried this:

;Check if the script finds the Save button
If WinExists("Skype™ - Options", "[ClassnameNN:TNavigableButton7; TEXT:Save]") Then
MsgBox(0, "", "Message before save")
EndIf

; Save the changes
Opt("WinTitleMatchMode", 4)
ControlClick("Skype™- Options", "", "[ClassnameNN:TNavigableButton7; TEXT:Save]")

Using the Window info i got this information:

i always go with as little descriptive info as possible, so long as i am sure there are not going to be any other windows with similar info.

change the wintitlematchmode opt to match any substring in the title then go with basics (assuming the controlID does not change also...

Opt("WinTitleMatchMode", 2) ;Matches any substring in the title
ControlClick("Options", "", "199210")
