Is there something wrong with Purchase Order Payment?

I have tried updating a Purchase Order on an existing form and tried creating a new one.  Every time I get the following error when I try to preview it on your site.

../../js/builder/question_definitions.js:2338: TypeError: Cannot call method 'split' of undefined var splist = opt.specialPrices.split(',') ^ TypeError: Cannot call method 'split' of undefined at Object.BuildSource.createInputHTML (../../js/builder/question_definitions.js:2338:72) at Object.BuildSource.createHTMLCode (../../js/builder/build_source.js:1720:30) at Object.createCSS [as createFullCode] (../../js/builder/build_source.js:957:27) at Object.BuildSource.getCode (../../js/builder/build_source.js:758:36) at v8_build_source.js:61:30

Hi,

May I ask which particular form you're having troubles with?
