I’m wrapping up a few Thunkable labs and need a quick assist on the programming side. The screens are already designed; what’s missing is reliable form validation and clean user-input handling. Here’s what I’m after: • Build the logic blocks that check each input before submission. • Display clear error messages when data is missing or invalid. • Keep the flow snappy so users can correct entries without leaving the screen. I’ll share the current .thunkable file and a short list of the fields that must be validated. A concise walkthrough of the changes—screenshots or brief notes—is enough documentation for me. If you’ve tackled input handling in Thunkable before, this will be a quick job.
