Before Going Live:
Problem: "Zap says successful but no data in Notion" Fix: Check field name spelling in Tally - they must match Notion exactly (including spaces and capitalization)
Problem: "Some fields are empty in Notion" Fix: In Zapier, make sure you're mapping Tally fields, not just typing field names
Problem: "Dates look weird" Fix: Use Zapier's "Formatter" to convert dates to YYYY-MM-DD format
Problem: "Duplicate entries appearing" Fix: Check Zapier task history - it might be running the same submission multiple times
Problem: "Zap suddenly stopped working" Fix: Check if Tally form was edited - any field name changes break the connection
