I am having a dynamic table structure below.

productList is having Product objects. I need to take the price value (productUnitPrice) out of Product object and assign to the 'txtUnitPrice' text box based on the selected product. I have stuck with the below code. Can you help me to proceed further?

Why not just access the select box directly (use its "styleId" attribute) and grab its value and set it to the text box?

I'd *strongly* recommend using a JavaScript library like jQuery, Prototype, etc.

I'm also moving this to HTML and JavaScript as this seems to be more a JavaScript/DOM issue than Struts, at least once you use the styleId attribute.
