Help with WHILE loops

Help with WHILE loops

Help with WHILE loops

(OP)
I am very inexperienced with while loops.  I am trying to write a loop that checks all the answers in a vector and if they are "OK" then it outputs "OK".  I keep getting an "array index invalid for this array problem".  I have written a simplified example of this problem to post here.  If someone could please take a look and explain what I am doing wrong it would be greatly appreciated.  I believe it is due to my lack of knowledge/experience with using a while loop altogether.  Thank you

RE: Help with WHILE loops

I don't see where you assign any value to "vec".  If I make start and end different from each other the error goes away and veclocation has a value in the output (the value is the next cell after the end of the while).

(OP)
well vec is not defined because I am using it as a function and therefore it isnt required to be defined.  The origin has something to do with this problem as if i set the origin to zero in worksheet preferences both work.  I think I have some sort of misunderstanding of the array indexing that I was hoping someone could clarify

RE: Help with WHILE loops

(OP)
IRstuff thank you.  I realize what is wrong now.  To fix it I am guessing there needs to be an otherwise statement added to the IF statement but I can't seem to get that to work.  Any ideas of what i can do
