Error on XLS form

your form cannot be deployed because it contains errors:

ODK Validate Errors: >> XForm is invalid. See above for the errors. : Cycle detected in form’s relevant and calculation logic! The following nodes are likely involved in the loop: ${layers_pre} ${incubators_pre} ${broiler_pre} ${slaughter_pre} The following files failed validation: ${tmps5s08n_p} Result: Invalid

i received this message and I tried to solve it, but I could not

I would suggest you test your XLS form here and progressively resolve every error mentioned as you continously check on the link until you solve all the errors.
