WooCommerce Calculator Plugin Migration

I have a fully-functioning price calculator from a previous WordPress website and need it moved to my current site without losing any of its logic or WooCommerce integration.

What I already have
• The original calculator files, settings, and styling
• A price-based logic set with product-specific conditions (I’ll supply the exact rules)
• WooCommerce running on the new site

What I need from you
• Install or port the calculator code/plugin to the new WordPress instance
• Re-link it to the correct product pages so users can enter their values, see the live price, and add the configured item straight to the basket
• Preserve all existing conditional pricing rules and verify they calculate accurately
• Match the look and feel of the current theme
• Test the full flow—from input to cart—to be sure checkout totals are correct

I’ll provide WP admin access, the original site backup, and a list of the pricing conditions. A short hand-off guide or screencast showing where you made changes will wrap up the job.


have attached 2 files - calculator-functions.php (where this is set up)

and calculator.js (where i think it's not linking to this correctly)?
