more than 1 function in cfform tag "onSubmit"

i need to call atleast 3 javascript functions in a form

using "onSubmit" works fine with one function but when i try to add another nothing happens....

<cfform

action="postpage.cfm" method="POST"

target="_self"

onsubmit="if(document.getElementById('Agree').checked) { return true; } else { alert('You must agree to the Terms and Conditions'); return false; }">

"return checkEmail(this);" is one of the funtions. it checks to see if 2 cfinputs are the same

how do i add multiple functions to onSubmit

tnx in advance
