We have close to 100 funds setup for our organization's Online Express form. Five to six times per month we get unexpected or (or obviously unintended) donations for the very first option in the dropdown menu that's selected by default.  Over the last two years when we've been suspicious that the donation was unintended, we've contacted these donors to confirm their gift, and 100% of the time it turns out that they had intended to give to another fund but overlooked the dropdown menu. 

This could be resolved by having the option to enable something like "Select Fund" be the first line in the drop down, and making the field required, rather than having the first fund in the list be selected by default.
