Response inside a nested repeat loop

I have a loop for plots of land and a loop of subplots inside it. Now, inside each subplot I have seasons with select_one option for the major crop grown in it.
Say: Plot 1 has:
subplot 1 with maize in 2020 long rains
subplot 1 with beans in 2020 short rains
subplot 2 with maize in 2020 long rains
subplot 2 with beans in 2020 short rains
Plot 2 has:
subplot 1 with maize in 2020 long rains
subplot 1 with beans in 2020 short rains
subplot 2 with maize in 2020 long rains
subplot 2 with beans in 2020 short rains
Now, how do I check that a user chose for example maize at any given subplot in any given season outside the loop.
Any help is highly appreciated

The two last questions in my survey should only appear if the user selected maize and beans respectively at any one time in the survey but how can i achieve this please? I am stuckaccessing value instance outside nested loop.xlsx (10.5 KB)
