Conditional System Exec with Initialization

[MikeNguyen]

Hi Yameada, thanks for the clarify. I might have swapped the concept of row and column earlier; What I’m trying is to read number of row inputted to pin point the last row for the number of for-loop to run (the last “end” at second column indicate number of loop), with the number of row varying between run and not making the user count the number of row manually. Number of column will be constant, as it contain three fixed datatype. (Could be 4-5 in the future)

I suspect the use of Local variable to be the source of my problem. I've read a few post about how not to use it, but still haven't really understand how to do similar thing without it. I can't find the loop indicator for the while loop to set a stop function, nor get the for loop to work. For the for loop, I can see that it is parsing the right data to the N, but the loop just sit there and literally do nothing; would it be because the time it takes for the data to arrive at loop count it's later than when the data is fed in to the loop's border?
