Hi what version of open office are you running because PDT token isn't required in newer versions. set transaction mode to sales I enable debug mode so if there are any problems I can see them in the errors log. Set the boxes under neath Total to pending or proccessing. as for the clients paying with paypal or credit card this is done in pay pal.
log into paypal and click on the word profile. In the left hand column click on my selling tools choose website preferences then do the following
1 click on atuo return
2 put in the url of your website including
http://www.
3 turn payment data transfer on
4 turn Encrypted Website Payments off
5 PayPal Account Optional turn this on (this gives clients the choose of paying with paypal or credit card)
6 turn PayPal Express Checkout Settings off
save the above then click on PayPal button language encoding (buttom of page under more selling tools)
choose more options and change code setting to UTF-8
answer yes to "Do you want to use the same encoding for data sent from PayPal to you (e.g. IPN, downloadable logs, emails)?"
then click save
under selling tools go to Instant payment notifications
click on update and choose edit settings put in the full web address of your store and save if your store is in a seperate folder make sure you inlcude that ie "
http://www.mywebsite.com/store/"
Hope all that helps
