how would i get the end part of the name with a script?

The parameter names I used aren't the ones in the wiki, they weren't very descriptive so I made my own

sub is short for substring

string.sub(target, starting, ending) will return substring from string target starting at starting and ending at ending. Note that you don't need to provide ending, it will default to the length of the string if you don't need it.

Examples with string.sub

print(string.sub("Hello", 2, 4)) --> ell
print(string.sub("World", 1)) --> World
print(string.sub("foo bar", 2, 4)) --> oo b

If starting is negative, it will start from the end of the string rather than the start, so string.sub("Hello", -1) would return o because it is the last character.

print(string.sub("Lua", -1)) --> a
print(string.sub("strings", -2)) --> gs (last 2 characters) 

So to answer your question you might want to use string.sub("Part For MHaven1", 9)

Or you could use string patterns and find it but I think sub would be a bit easier.
