I am a little lost with this function procedure that sounds pretty straightforward, but otherwise i am clueless. I need to create a VBA function procedure for the inverse sine of a function that unlike excel, actually converts it to degrees. It also needs to be able to check to determine if the function argument provided by the user is a legitimate value for the inverse sine function. If it is not, then the output of the function (NOT a message box) should be a statement informing the user of the problem.
