In this video I been watching to add a inventory system, Part 6. I completed a Function call RefreshSlot. For some reason this in the video doesn’t say I need a return value, How ever I’m getting an error on my project that a value must be returned. The 1st screen shot is from the video.
The error says that a bound function is not found. Check the designer panel for a variable called “ItemQty” (should be a text) and make sure the bonded function is valid.
I’m pretty sure you deleted the function at some point and that’s why it can’t find it anymore.
