Need an input field not select PHP HELP

Hello All,
Just hoping someone can help me out I've spent hours trying to figure this one out...
I need to edit the following PHP so I can have the user enter an amount rather then having to select from a drop down list.
    <?
include("includes.php");
session_start(); 
/**************************************************************************************************

*
* Displays details of the products and allows the user to enter a number of each item to buy.  
* It then validates the selection and forwards the user to the customer details page.

// Check for the proceed button click, and if so, go validate the order
if ($_REQUEST["navigate"]=="proceed"){
    /** We need the user to have selected at least one item, so let's see what they've chosen **
    *** by looping through the submitted Quanity fields **/
    $strCart="";
    for ($iLoop=1; $iLoop <= count($arrProducts); $iLoop++) {
        $strQuantity = "Quantity" . $iLoop;
        $strThisQuantity=$_REQUEST[$strQuantity];
        if ($strThisQuantity>0) {
            $strCart=$strCart . $strThisQuantity . ",";
        }
    }

    if (strlen($strCart)==0){
        // Nothing was selected, so simply redesiplay the page with an error
        $strPageError="You did not select an amount to charge.  Please select at least &pound;1 to charge.";
        $_SESSION["strCart"]="";
    }
    else  { 
        // Save the cart to the session object
        $_SESSION["strCart"]=$strCart;
        // Proceed to the customer details screen
        ob_end_flush();
        redirect("customerDetails.php");
    } 
}
else if ($_REQUEST["navigate"]=="back") {
    ob_end_flush();
    redirect("welcome.php");
}

// If we have a cart in the session, then we'll show the selected items here **
$strCart=$_SESSION["strCart"];

                <a href="javascript:submitForm('mainForm','proceed');" title="Submit the order details" style="float: right;"><img src="images/proceed.gif" alt="Proceed to the next page" border="0" /></a>
            </div>
            </form>
        </div>
    </div>
</body>
</html>
Am I right in think the details are passed into a variable called $strCart? I'm new to PHP any help would be greatly appreciated!
