Hi all

Very new to the art of VBA and trying to develop some web scraping over a supermarket site to return current prices from a spreadsheet list of items. I have the below but can't get the data to return properly - am seeing the Runtime Error 438 at the point I'm trying to get data from the class element "pricePerUnit". Any help gratefully received!

Thanks

Dim objIE As InternetExplorer 'special object variable representing the IE browser
Dim aEle As HTMLLinkElement 'special object variable for an <a> (link) element
Dim bEle As HTMLLinkElement 'special object variable for an <b> (link) element
Dim y As Integer 'integer variable we'll use as a counter
Dim result As String 'string variable that will hold our result link
