What do you mean by not working.

rabbit:

the 1st case is : (in function validation)
for example,i didn't enter any information in one of the text box.when i click submit, it should display an alert box saying that, "Please fill in 'Name' textbox" for example...but, instead of that, it just go to new window and display "Data have been save" or "Record existed". Thus, there will be an empty space in a database.

the 2nd case is: (in function validateForm)
it should display an alert box when we entered wrong email....it act as an email validation. as we see, in function validation, i had already put the email validation as a comment so that the system will not be malfunction. before this, i had tried the function validateForm in another page, and it is working.so i would like to combine it with the other textbox validation that is function validation.

3rd cases : (function valForm)
this function should be able to validate all textbox in this register.php page(the code for register.php page is as above code that i had post in the question)which including the email validation and name,department etc.unluckly it is not working as i expected. so, i would like to ask your opinion on what should i do so that both function is working.

1) Your onsubmit called function never returns true or false depending on the return values of the functions that it calls. That's why it always submits. Also, you never see the alerts because ValidateForm fails to run correctly.

2) ValidateForm and echeck is not valid javascript. I suspect in the other page you were using vbscript. They are not the same. You need to port those functions to javascript.

3) This is directly related to the previous issues.
