I have a project where I want to be able to multiply 2 values from a database.
So I have a combo box where the user is able to select from a set of data.
This displays the data relating to the selected row in text boxes on the windows form.
There is a button that is clicked that needs to multiply the one column by another so essentially the text from box 1 against the text from box 2.
I have tried a few ways of doing this now but keep getting errors stating the number must be less than infinity or that the source must be convertible to the destination type.
I know this is probably a school boy error but I am admitting defeat...
