# Youseful Software - FileMaker sample script
# Script name: Youseful - PHP totals
# Plug-in: YsflPHP.fmx64 (Windows x64)
# Setup: Install PHP 8 or later for Windows. If discovery fails, add a separate php=<full path to php.exe> option line before param=. No fields needed. JSON is passed through $fm_param.
# Expected: {"count":2,"total":37} (JSON spacing and key order may differ).
# Format: UTF-8 Script Workspace step listing. Add the steps manually; this is not an importable FileMaker file.
# Lines beginning with # are notes; optionally add them as Comment steps.
# Preserve calculation quotes, backslashes, and paragraph symbols exactly.
