Instructions and Help about Why Form 8815 Verification

Hi this is Ralph and in this video I want to expand a little bit on the check for blank function that I just did a little bit ago in the previous video so in my last video we have a simple form we just load this up on our yield web page here so I had a simple form first name and last name and when the user tried to submit the form it would check to see if the first name field was blank and if it was it would give him an alert and it would color the border of that box red okay I'm just going to read for element it's tops the form so let me just kind of refresh that head back over to my editor so that simply checks for the value of the first name box but now I want to check for the values of both boxes to see if either of them are blank so what I'm going to do this time is I'm going to expand on my existing function so I'm going to go ahead and start off with in my check for blank function I'm going to declare a variable this variable is going to be called error message and it's going to be equal to nothing it's going to be equal to empty so there is no error message at the beginning then we're going to go through our function here the variable message starts with nothing if the first name field is blank then what I'm going to do instead of just providing an alert here I'm going to append so that means I'm going to do a plus equals count plus I'm sorry I'm going to do an error message plus equals and then...
