supa is not a varible, is the entire js function
chrome and firefox show this error on their js consoles:
"Uncaught ReferenceError: enviar_datos is not defined
at HTMLInputElement.onclick (index.php?menu=campaign_out&action=load_contacts&id_campaign=1:1439)"
also, looking on the code in https://github.com/IssabelFoundation/callcenter
the file "modules/campaign_out/themes/default/load_contacts.tpl" seems to be the responsible of the form's html code, and it doesn't contain any js script, and in
"<input class="button" type="submit" name="save" value="{$SAVE}" onclick="return enviar_datos();" />"
the post ovbiusly is never done.
