SQLExport / SQLImport = Cannot read property 'drops' of undefined

Hi, I have been using SQLExport and SQLImport function which has been working ok, but for some reason today I get this error when I run the SQLImport

appstudioFunctions.js:351 Uncaught TypeError: Cannot read property 'drops' of undefined
    at appstudioFunctions.js:351

Which seems to be related to this NSB function:

350: db.transaction(function (tx) {
351:        for (i = 0; i < json.ddl.drops.length; i++) {
352:            tx.executeSql(json.ddl.drops[i], [], function (t, r) {},
353:                NSB._sqlError(json.ddl.drops[i]));

It seems the SQLExport function might not actually be exporting it as the resulting file size is only 1kb.

Fixed, was my error.
