/*this works for the MySecondaryArray having only exactly 3 fields.
i'm sure it could be done so that it adjusts automatically
but i didnt need it to so i didnt bother.
the text file goes like this :
myTextFileVar=this;;that::the next;;\n\nthis2;;that2:
:the next2;;\n\nthis3;;3that::3the next& where each "\n"
is a carrige return in the text file meaning there is
1 line between listed items to make it easier to use,
and "&" is the absolute last character to indicate the
end of the variable. if lost use trace actions to figure out what does what. enjoy.*/
