I have several text fields on page that I would like to make calculations based on if there is a number input in one of the fields.
So, if the price field is populated, the sale price field would populate using a function to do the calculation.
Now, how do I write the code for this to occur? I know how to get the function to fire based on clicking a submit button, but not sure how to do it simply based on a number keyed into the one field.
Is this possible and if so, how? Thanks a ton.
