I am looping through a datatable in the following manner:
I want to create variable that houses the previous value of PHYID, (basically the value before the current value it finds in the regular loop) to use as a comparison later.
How would I do this in code?
Define an index inside the loop.Then you can assign as follows.
What would I set the index as? 0?
It will start from default 0. You create that index in the for, it will increase as the loop continues. When you stop according to a condition, -1 of this index will bring you the previous row.
Code worked fine but then it threw an error
“Assign: There is no row at position -1.”
What would I do to bypass the initial header?
By adding a condition, you can say don’t do this assign operation in case index = 0.
Thank you! This seems to work
