Using a Variable in a $_POST

I'm currently trying to develope a system that allows users to develop tests. These tests can range from 10 questions to 100 questions. To cope with the different size I setup each test as its own table.

Now to read the input from the forms generated by this test I am using a while loop:

$TestData = @mssql_query("SELECT Id FROM Course$CourseId$TestType");

$Counter = 1;
while ($TData = mssql_fetch_array($TestData))
{
$QuestionId = htmlspecialchars($TData["Id"]);
$Question$Counter = $_POST["$QuestionId"];
$Counter++;
}

How can I get the $QuestionId to be read as a number and not a variable. cause it spits back "..parse error, unexpected T_VARIABLE.."

what line is the problem at

Your problem's in the second line within your while statement. You're jamming two variables together and trying to assign the $_POST value to the jammed-together variables. You'll need to use an array or something instead.

Incidentally, it's probably not the best idea to have a different table for each test. Better to have a test table that holds general info (title, etc.) and a questions table that has a test_id field for each row mapping the row's question to the given test.

The problem is with
$Question$Counter = $_POST["$QuestionId"];

i have a poll script i wrote, if u want ill post it so u can get the basic idea of what houston was saying.

Thanks I got it to work, also thanks for the advice on my database setup...
