Error During imputation submit

Hello

When entering imputations, an error appears. I looked at the log and increased variable "max_input_var" 10000 but without effect. Would you have a solution? It looks like a limit because it is when adding assignment that the problem occurred

It works. Thank you very much. I wanted an answer before but I had not found the right topic
