Replace string in selected Text ? and Eval like function - wildma

1. I see there is a quick replace option but it provides no option for
only on selected text??

2. I have a cell with the value 2 in it. I want that value to drive
the column name i will be using in an expression. In other words, this
is my expression if I hard code it.


=(Fields!Month2Active.Value/Fields!Month2Days.Value) * Fields!
fees.Value

but the express will look like this on the column next to it:

=(Fields!Month3Active.Value/Fields!Month3Days.Value) * Fields!
fees.Value

any way to do this dynamically?

thanks for any help or information.
