Can any one help me on this ?RollUp Summary field can be multiplied in a visual force page.Based on the condition ,I need the value of the RollUp summary to get multipled (0.01) in wrapper class .

"Subtotal\_\_c" and "Non\_Pick\_Total\_\_c" are Roll up summary fields on Opportunity Object.They give the "Sum" of Opportunity Product aggregates on Extension Field.Extension(Extension=qty\*1) is a Formula field data type as Currency on Opportunity Product.

The issue I'm having is that the "Extension" field value is getting calculated based on the formula field but it should get calculated as per the changes made in the visual force page and display (Extension = Qty\*0.01) on the subtotal.

Condition :

If the product line for the product selected in opportunity items is ‘DIE’ make following changes .

1) unit price should change to $.01.

2)Unit price just change on the PDF display only and with extended amount which will be quantity times .01.

3)Subtotal\_\_c=Non\_Pick\_Total\_\_c

How do I achieve this?I shall appreciate your help.
