Javascript error when adding new stripe form

While attempting to add a new stripe form- upon selecting certain forms from the drop-down menu I was getting an error stating that there was no object method “replace” for the variable “fieldValue”. This was because for some reason, certain forms were outputting numbers instead of strings. I added the line fieldValue = fieldValue.toString(); to line 1789. I hope this helps any one else out there. And if this seems integral to the plugin, perhaps it could be rolled out in an update.

Thanks!
Jake
