Hi. I"ve a XLSX files. The XLSX files contain 2 sheets. Each sheets have common field (sample_ID). The first sheet is a description of the sampler, like the report name. In the second sheet it's the result of station. For each station it'S have many result ( 1 to M relation). I want to update a field in the second sheets with the value of the first sheet. But i have a error message (check the Capture files). Thank for help :)
