Fix sub-workflow dropdown: \nopen \"Parse msg and save to Sheets\" node (which is an n8n sub-workflow executor tool) and choose the SAME workflow in the dropdown. it will allow n8n to call \"Workflow Input Trigger\" properly when needed.\n\n\n### 3. Activate the workflow to make chat work properly.\nSent message to chat, something like \"car wash; 59.3 usd; 25 jan 2024\"\n\nyou should get a response:\nYour expense saved, here is the output of save sub-workflow:{\"cost\":59.3,\"descr\":\"car wash\",\"date\":\"2024-01-25\",\"msg\":\"car wash; 59.3 usd; 25 jan 2024\"}\n\nand new row in Google sheets should be inserted!"
