I've been looking everywhere to see what's the right approach, and I can't find anything in english.stackexchange.com or other sites.
I have the following sentence:
Our customers love this feature, but we know it's not always that easy if you don't have previous experience of creating rating scales.
I'm wondering if the above is correct, or if this is correct instead:
Our customers love this feature, but we know it's not always that easy if you don't have previous experience in creating rating scales.
Notice the difference in the use of “of” vs. “in”. Which one is the correct one in this sentence?
