Subflow If Statement Evaluated - False

[CarlittoS]

I'm trying to get my subflow to trigger an If Statement, but only if a change is made within the catalog SCTASK. Is this possible?
If "No" is selected, the flow should go to task 6 only then close RITM, but if "Yes" is selected, the flow should go to task 6 then task 7 before closing the RITM. 

The subflow context shows that the Flow Logic "Evaluated - False" even though the condition (Is not Empty) was met, but it "Evaluated - True" when the condition (Is Empty) was not met. 

The condition is reading as empty even though information is filled out in the SCTASK, so does the If Statement in a subflow only work on fields filled out on the initial form? I need the condition to trigger from the SCTASK

Why not add a flow variable for the orignal cost and a variable for the cost after evaluation and do your 'if' logic based on variable a != variable b and an else if not (or the other way around, whatever works best for you.

Thank you for the suggestion! I tried that, but the problem is that the condition always runs true, because it shows them both as empty:

Maybe I am missing something when it comes to pulling the Input data from the SCTASK to the Subflow? The data is just empty no matter what they conditions are.

Log the inputs. Because your result is nothing = nothing and that shouldn't be the case. If the variable is filled, you should be having the input, or you are setting the input wrong.

The variable is not filled on the initial submission:  

I'm trying to get the input from the SCTASK, not the front-end user form
Essentially: IF someone on the backend selects "No" on the 5th SCTASK field for "cost_difference" THEN the flow has 1 task left, but if "Yes" is selected then the flow has two steps left.

Maybe there is a way to connect the SCTASK input to the subflow that I am missing, could you help me with that?
