Creating VBScript command dynamically using ASP passed value

ok this will be the death of me! lol

my ASP code creates a form and an array of chekbox with this statement response.write "<input type='checkbox' name='chkProduct" & Cstr(counter) & "' value='delete'>" all goes well and i also have a button that points to a VBScript function passing one parameter the counter start value so i can loop throught the checkboxs on the client side and determine if checked or not.
Ok i can display my command "document.frmProductCart.chkProduct & (Cstr(counter)) & .checked" as a string in alert but cannot make it as a command like it should be, anyone got any pointers ?
thx you ahead of time...

I have include the page in question. Sry i have not put any comments in it yet...

I figured it out...
the trick was to use the Elements function like so
alert document.frmProductCart.elements(counter).checked
but be carefull with this as all types inputed in a forma are an element this works for me right now because i only have checkboxs and textboxes and checked function returns nothing on a textbox so it only checks the chkboxes ... get it ? lol

this is the code:
the chkbox:
response.write "<input type='checkbox' name='chkProduct' value='delete'>"
the button:
response.write "<INPUT TYPE='button' name='cmdDelete' value=' Delete ' onclick='DeleteProduct(" & Session("ProductCount") & ")'>"
and the function:
sub DeleteProduct(ProductCount)
dim counter
counter = ProductCount
do while counter > 0
if document.frmProductCart.elements(counter).checked then
/*code when checked*/
else
/*code when false*/
end if
counter = counter - 1
loop
end sub

sry admin.. theyr an error in the previous code the elements function is an array thuse starting ar 0 and not 1 so a -1 should be place where the counter is inside the loop
