I need some help making my form more efficient. Right now, I have a textbox "Currency Rate" and a combobox "Currency Type". The user chooses a bunch of items that he wants to buy and all the prices show up by default in dollar. Then let's say he wants to convert to Euro. He would enter the rate in tbCurrencyRate and then choose "Euro" in the combobox. My code then checks which currency he is converting from and multiplies or divides all the prices by the value in the textbox acccordingly. This works very well, but can be very confusing for the user, having to remember to first put the rate in and then choose the Currency Type. It just doesn't seem so smooth. Any ideas to make this smoother?
