attempt to index global 'dispatchTable'

[mg20023]

I've had this problem for a long time now and I can't seem to figure it out.

The error I receive is: c_dispatch.lua:84: attempt to index global 'dispatchTable' (a nil value)

Help would be appreciated

The script is telling you that processedName is nil. You're trying to assign/call a table's key as a nil value. First try to see if processedName isn't nil, if it's not, then get the type. Something like this would do;

replace;

if type(dispatchTable[processedName]) == "table" then 

with;

if processedName and type(dispatchTable[processedName]) == "table" then

It did help BUT now another error came:

c_dispatch.lue:131: attempt to index global 'dispatchTable' (a nil value)

It did help BUT now another error came:

c_dispatch.lue:131: attempt to index global 'dispatchTable' (a nil value)

That's the same error, just about this piece;

if not dispatchTable[processedName] then 
                    dispatchTable[processedName] = { } 
                end 

Add a new check in there to see if you actually got a processedName before trying to create a table for it. Also, make sure that you're actually putting something in the processedName because it might give you unexpected results.
