I have an existing Excel workbook that currently requires manual input of addition, subtraction, multiplication, and division formulas across several sheets. I need these basic arithmetic operations to run automatically as soon as new rows of data are entered, so totals, variances, and ratios update instantly without any further action from me. Please build the automation directly inside the file—VBA, dynamic array formulas, or another native Excel approach is fine as long as it works on both Windows and macOS versions of Office 365 without additional add-ins. Once complete I should be able to drop fresh data into the designated columns and see every calculated field refresh correctly. Deliverables • The updated workbook with the automation in place • A short note...

I need a application that lets me tag every palm tree on the farm with its own QR code. The flow is straightforward: I enter a new tree, the program generates and prints a unique code, we fix the label in the field, and any time the code is scanned the system instantly pulls up that tree’s record so we can add or edit details—species, current growth notes, location in the plot, or any other data points we decide to track. The software must run smoothly on Windows 10 laptops and work offline, storing its data in a lightweight local database with an easy way to back up or sync when we have a connection. A clean, uncluttered interface with large buttons is essential because farm staff will be using it; think Electron, WPF, .NET, JavaFX or whatev...

When someone reorders and pays or uses a promo code to discount their order to $0, the payment is not noted on the card and the email is not triggered to let me know someone submitted their order. This functionality works perfectly when someone does an original order and pays the deposit and goes through the whole design process and pays their full amount within the website. However, if a previous client does a reorder of an order from before the payment integration, there is no email being triggered when they pay for their order. Also, if a league or school that pays my via check in the mail uses a promo code to make their balance zero dollars so that they can submit their order online but pay off-line, an email is not triggered. I need an email that says ready for productio...

I’m looking for clean, well-structured Python code that lets me spin up a small website whose main purpose is content management. Framework choice is up to you—Django, Flask, FastAPI with Jinja, or something similar—so long as the final result is easy for me to unzip, install dependencies, run migrations (if any), and start serving content. What matters most is that I can log in as an admin, create new entries, edit them later, delete when necessary, and have those changes reflected immediately on the public-facing pages. A minimal, intuitive interface is preferred over heavy design; raw HTML/CSS is fine as long as the CRUD workflow is solid. Please include: • Complete source code with clear structure (models, views / routes, templates, static ...
