Freeform - get option label & value on submissions page
The code above is correct, but it turns out there was an actual bug in the code if you had a number as the option value.

This affects Freeform 1.5.1 and earlier. The next version (1.5.2) of Freeform will include a fix for this. If anyone needs a patched copy of Freeform before 1.5.2 is available, just contact us via our support form. :)
