lighter help!!!

i hope this is allowed here🙏i assume someone here must know stuff about lighters

i recently got this lighter at the flea market the other day. the man who sold it to me refilled it with lighter fluid so i know that’s full. it sparks when i try to light it but it won’t catch a flame. is there an easy fix or should i take it into a shop? (if there even is one around me). idk if there’s flint or a new wick i possibly need? thank you:)
