Is there a way to disable submit button at startup and enable it if both options are selected and disable again if one of them (or both) are returned to its original state (nothing)?

Set your button to be disabled by default. Then add an onchange event handler to your select element. The handler should determine what is selected, and then enable/disable your submit button per your requirements.

Here is the source in case anyone want to learn:

<script type="text/javascript">
function dis_ena_submit()
if(document.acc_ctrl.add_access.options[0].selected document.acc_ctrl.add_assoc.options[0].selected)
//Disables submit button
//Enables submit button

<body id="access_control" onload="document.forms[0].grant_button.disabled=true;">
<select id="label_add_access" name="add_access" onChange="dis_ena_submit('add_access');">
<select id="label_add_assoc" name="add_assoc" onChange="dis_ena_submit('add_assoc');">
<input type="submit" value="Grant" name="grant_button" />
<input type="reset" onclick="document.forms[0].grant_button.disabled=true;"/>
