Problem with Web Searches Using Clipboard

Currently using DNS 14.0

Every time I perform a search only the first
word is pasted into the Google search box. For example, if the clipboard contains the phrase "the great barrier reef" only the word "the" is pasted into the Google search engine. I've tried using other sites other than Google and the same thing happens on each and every one of them. Only the first word from the contents of the clipboard or ever pasted.

I tried searching the forums but couldn't find anyone else that was having this problem. I'm hoping someone can assist.

Here is the code I'm using:

Sub Main
a = Clipboard
Wait 1.0
ShellExecute "https://www.google.com/search?hl=en&as_q=" & a
End Sub
