i want to display a attribute just below to the price in product view page and should be dependable with price. that is I select one from attribute price should change.
This sounds like a case for configurable products.
For example, you create three simple products "T-Shirt M", "T-Shirt L" and "T-Shirt S" with the respective "size" attribute.
Then you create a configurable product, select "size" as configurable attribute and choose the three simple products from above as associated products. For each simple product you can choose a price difference at this step.
