testing for empty table

Run-time error
World: test
Function/Sub: Prompt called by trigger
Reason: processing trigger "Prompt"
[string "Script file"]:6: bad argument #1 to 'next' (table expected, got nil)

this error resulted when testing for empty table with this code

function Prompt (thename, theoutput, wildcards, line)
iHP = wildcards [1]
iMovement = wildcards [2]
iCoins = wildcards [3]
if next(mobs) == nil then
mobsRemaining ()

argument #1 to next is mobs

So next must be passed a table. You passed it mobs, which is apparently nil and not a table.

Maybe test for nil first (ie. no table) and then next (mobs) to see if it is a table, but an empty one.

Thanks, Testing for nil then testing for empty table worked.
