I'm getting stuck at vba runtime error 424

I'm getting

run-time error 424

and I don't know how to fix it.

My previous question I posted ; How to scrape specific part of online english dictionary?

My final goal is to get result like this;

    A          B
beginning   bɪˈɡɪnɪŋ
behalf      bɪˈhæf
behave      bɪˈheɪv
behaviour   bɪˈheɪvjər
belong      bɪˈlɔːŋ
below       bɪˈloʊ
bird        bɜːrd
biscuit     ˈbɪskɪt

Here's code I wrote, and it's mostly based on someone else's code I found on internet.

'   Microsoft ActiveX Data Objects x.x Library
'   Microsoft XML, v3.0
'   Microsoft VBScript Regular Expressions
