This is a part of my code for a shoppingcart. I have been trying to get the value from the text box which is the quantity for this cart. - <input type="text" name=<%=numbername[j]%> size="2" > But the values are static from this page. When I enter the values from the page, it did not give the values i enter instead the static values appears. Can anyone know a way to get the value as entered in this for loops? Please help by take a look at this jsp code above. I have been trying many ways in many days but no answere. Can anyone help?
Can you explain this in a little more detail. I can help you out but I need more information on what it is you are trying to do. That and a larger chunck of code would help. I see variables that you are using but dont know how you have created them which may be important.

When you submit the the page hope you are getting the numbername values as request.getParameter().
If so then the static initiation what you have done of this string array should be done before the assigning values to it from the request.getParameter..
That will probably solve the problem.

This is the code that is your problem. You are using an anchor tag to do the actuall submitting of your parameters but you have them hardcoded so numname is always 1. You are not making any kind of reference to the form elements.

Then how do I enter and pass the values cause this is a for loop. I assign the value by this loop.?thanks
instead of the jsp variable use the document.form.fieldname
