How do I insert a key and value into a dictionary while the game's running?
1 | table[#table+1] = player.Name.."="..ds:GetAsync(player.userId) or 0 |
2 |
3 | --attempt to concatenate a nil value |
I know it's erroring because I'm inserting a string and a number obviously which doesn't make sense for a normal table. I want to create a key and value inside of a dictionary..

The problem here is precedence.
or is the lowest precedence, meaning the expression is interpreted as
1 | ( player.Name .. "=" .. ds:GetAsync(player.userId) ) or 0 |
You just need explicit parenthesis:
1 | player.Name .. "=" .. (ds:GetAsync(player.userId) or 0) |
The error should have hinted this -- it said you're concatenating nil. Concatenating is the .. operator; the only thing near a .. that could be nil is ds:GetAsync.
Aside: This isn't a dictionary. This is a list.
You should consider using table.insert instead of tab[#tab]. You also really shouldn't use the variable name table, because it will cover up the table library and maybe mess you up later.

Wow thank you, although I have re-done the layout of what I'm scripting, (although small) this has taught me something more about scripting. (The position of the parenthesis) <3 magiccube3 115 — 9y
