Variable type question

lets say that
m = 15
but i need it to be
m = "15"
how can i do that?
i cant just change the 15 because its a variable thanks!

Split into new topic.

Are you looking for tostring()?

Let me try this again
Here's the code
Peripheral.wrap("back")
Rednet.open("back")
M = turtle.getFuelLevel()
Rednet.send(6,M)
Print(M)

Ok so it sends perfect but it sends as
4567
Instead of
"4567"
How can I fix this?

tostring() will convert things to a string.

ex:
x = 15
print(tostring(x))

Ok so then how do I send the tostring via Rednet?

Man, read the PIL.

rednet.send(6, tostring(M))

Thanks I've been using lua for awhile but still not an expert at it! :)/>
