I have two columns in a list on sharepoint 2010, [phone number] and [email address]. I need help writing an IF statement for the column validation for these two columns. I need to it basically be that one or the other of these fields has to be filled out
or a pop up message will prompt the user. So, if [phone number] is blank and [email address] is filled out then TRUE.
I am new to sharepoint and appreciate any help. Thank you.
