There occurs to be a syntax error which say “Parse error: syntax error, unexpected double-quote mark, expecting “-” or identifier or variable or number” while I am trying to proceed with
$tablequery = "SELECT * FROM purchases WHERE customerID='$_SESSION["custname"]'";

I tried to make $_SESSION["custname"] to a variable. But it did not help.
I am expecting to print values from a table to a table in HTML.
