1. Please don't post in HTML.

2. getText retrieves text from a Windows control using 
the handle to that control. data[location..3] will 
return a single character, not a handle.
Why are you using it here?

3. Match finds the location of a string within a longer 
string: 

if the longer string is "My Name Is Mudd", 
then match ("Name",longer_string) will return 4.
M=1
y=2
space=3
N=4

4.You say "I want to then pick the Name and to he data
following for value of Name."

This makes no sense. I am only guessing now, but 
if you want to return the portion of the string 
from "Name" on thru the end of the string, then 
try this:

location = match("Name",string)
substring = string[location..length(string)]

If that's not what you are trying to do, please 
try your question again.
