Please use the ID=<%ID%>string from the LinkTo value as is, don't replace the <%ID%> with a value, the web part is going to do that for you dynamically.
Just customize the http://……aspx part of the below link.
Please check the docs for more details.
http://…pageA.aspx?ID=<%ID%> .
If you get an error saying "The list item doesn't exist' then use LID instead of ID and change the ListForm ID property to LID. In the docs we talks about all these.
If you still have question let me know please.
