Hi everyone,

I am new to javascript and written the following script for the purpose of validating my opt-in form.

However,when I carried out a test by clicked on the submit button without filling in any field,to my suprise,it allowed for the submission without prompting any error message !

Please kindly review the following script and advice the errors in it.
