Is it possible to check an option/select box to see if it still has data in it?
I'd like to be able to stop a user from updating a file IF the field they are copying from still has content in it.
BOX 1 BOX 2
So the button will display an error message (e.g. you aint sent the entire lot over)
I've tried to attempt it but my mind cannot really handle anything more than (Check kettle for water, IF water equal or less than 1 cup full, then fill kettle with water, If kettle equal to or greater than 3 then STOP)
