Use field values to populate another checkbox on submit.
<p>How would I go about writing a javascipt that On Submit, would check if two fields are blank, and if they are NOT blank, then it would automatically set another field to "TRUE"? Example: </p>

<p>Invoice Table--
CustomerID,
InvoiceID,
Check,
Cash#,
Paid</p>

<p>I want the function to check if there are any values in Cash or Check# then check the Paid checkbox.</p>
