Line 72:

table.insert(data[name]['Knives'],knife)

I’ve been stuck on this issue since last night and I cannot figure it out for the life of me? Why does the output say its getting a string when I’m clearly calling the ‘Knives’ table in data[plr] ??

[Mystxry12 (Mystxry)]

Maybe try printing the data[name]["Knives"] as the data already saved might be invalid.

[vinceops (vince)]

Tried that already, data is valid

Problem Solved, I hopped on a voice call with Vinceops and the issue was that he saved the value as a string, not an array.

Your data is a string, not a table, as shown in the error.
