Subscript used on non-accessible variable (Webdriver)

[SkysLastChance 20]

I have seen some similar post, but not sure how to implement using Web-driver.

So my problem is I am looking for all instances of the word "yes" on my webpage. (chrome)

The problem is "yes" may be there once or even not at all. 

I understand why I am getting the error. Because it is not always a array. However, the error is causing my script to end. I don't want it to end the query. I just want it to continue on. 

Here is an example: This will click the first and second instance of "yes' on the webpage. (as long as it exists)

$sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//*[contains(text(),'Yes')]","",True) 
_WD_ElementAction($sSession, $sElement[0], 'click')
    Sleep (2000)
_WD_ElementAction($sSession, $sElement[1], 'click')

This is the error I am getting. 

"C:\Users\******\Desktop\Expanse Auto Reg Test.au3" (44) : ==> Subscript used on non-accessible variable.:

; Note that we usually say 'a' before array type variables
Local $aElement = _WD_FindElement(...)
; For each element in the array
For $i=0 To UBound($aElement) - 1
    ; Perform the action on that element, we access it with $i, which goes from 0, 1, 2, etc until the size of the array
    _WD_ElementAction($sSession, $aElement[$i], "click")
Next

Edit: You should probably be checking for @error after each _WD_ call if you aren't already

IsArray($array) will tell you if there is an array returned by the function and Ubound will tell you the number of occurrences found

I had to add some delay. probably a little overkill but it works. 

Thank you both!

Local $aElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//*[contains(text(),'Yes')]","",True)
; For each element in the array
For $i=0 To UBound($aElement) - 1
    ; Perform the action on that element, we access it with $i, which goes from 0, 1, 2, etc until the size of the array
    _WD_ElementAction($sSession, $aElement[$i], "click")
        If @error <> $_WD_ERROR_Success Then MsgBox(0, "Error","Could not click 'Yes' Button " & $i)
      Sleep (2000)
Next
