Autoit Badly formated variable or macro - autoit

Question

I am new to Autoit and tried to do this:
Local $stest = "C:\Program Files (x86)\test\test.exe";
Local $sPath;
runS($stest);
Func runS(String $sPath) {
this.$sPath = $sPath;
If FileExists($stest) {
Run($stest , "", #SW_SHOWMAXIMIZED)
}
}
And get this error:
(6) : ==> Badly formated variable or macro.:
I am just trying to write a parameter as a path in the function...

No lines in AutoIt end with a ";". The ";" is used for commenting in
AutoIt.
If statements must have a “then” statement.
Nothing in AutoIt is opened or closed with the curly braces “{}”.
Most statements are closed with semantic words like EndIf, EndFunc and
Wend.
Here is what your code should look like:
;$g_sTest is global variable because it is being declared outside of a function.
Global $g_sTest = "C:\Program Files (x86)\test\test.exe"
runS($stest)
;$sPath will be a local variable because it is being declared inside of the fuction.
Func runS($sPath)
If FileExists($sPath) Then
Run($sPath, "", #SW_SHOWMAXIMIZED)
EndIf
EndFunc
