For loop wont loop through array built from spread sheet

Question

im probably doing sonthing really silly but........
first i build and array out of data from a spreadsheet (RefLookup)
the spreadsheet contains 3 rows the top row is my label (to be returned later)
the second row it my maxmum value
the third row is my minimum value.
Ref in is my live feed of data to be looked up.
i then put this into a for loop, to loop through the array untill it finds which range of data the Ref in lies.....
then i simply stop the loop and output the index value.
this index value is the used to look up the spreadsheet data again and return the label for that index.
from what i can gather the code should.... work. but it doesnt seem to go passed the first itteration of the for loop 
any ideas?
please and thanks
John

Answer 1

You need to set the delimiter to comma, else you don't get all data. (read from spreadsheet file)
You are doing this way too complicated. Here's equivalent code. I am sure it can be simplified much more!  
You don't need the outer while loop. finding it once is sufficient. 
You probably want to add a "select" after the loop that selects NaN instead of the last value if nothing is found, based on the boolean.
