Can't access the pay source option – Budget Touch Review

Started with the desktop version of this program. Figuring out how to work with a credit card took a while & after two months I'm still not confidant that I do it correctly unless I pay the balance in full. Otherwise love the desktop version - makes it easy to see where the money needs to go & how much I have left to really spend. iPod touch version is another story - I can't seem to get the add-ons that would allow the mobile version to be useful. The add-on button is "disabled" & I can't figure out how to get it enabled. Tried the app store directly, am talking now with SnowMint. Would give the program more stars if the credit card part were easier to understand & if the mobile version came fully functional without having to do add-ons.
