And while it obviously handles contact details effortlessly, my question is what the best way to calculate a registration fee based on part-time attendance for the camp.</p> <p>I don't need it to accept payments, only to calculate what the part-time rate would be depending on which day they arrive, and which day they leave. Then to display this figure to the user, and record the value as part of the user's registration.</p> <p>Any suggestions on whether GF can handle this? </p>
