If I’m counting correctly, line 24 of puremom.txt is this:
*if ((breed = "Doberman") or (breed = "Rottweiler""))
Which has an extra quotation mark after Rottweiler. The extra mark probably counts as an “opening” quotation mark, and if it does, it has no “closing” quotation mark. Try removing that, re-saving the file, and testing again.
One thing I really hate about using ", is I always miss it when I accidently have a second one. Thank you. Getting new errors now but they are not related to this. Thanks!
