valuewhen is a built-in Pine Script function that returns the value of a specified series at the time when a given condition was true, for the nth most recent occurrence.

When working with Pine Script, encountering the "undeclared identifier" error is a common hurdle, especially for those transitioning between versions or writing complex scripts. This error means that your code is trying to use a variable or function name that Pine Script does not recognize because it hasn't been declared or is out of scope.

• Using variables before declaring them: If you reference a variable before it is defined, Pine Script will throw this error.
• Scope issues: Variables declared inside conditional blocks (like if statements) are only accessible within those blocks. Trying to use them outside causes the error.
• Version differences: Pine Script has evolved, and some identifiers have changed. For example, in Pine Script v4 and above, tickerid became syminfo.tickerid, and color names require the color. prefix (e.g., color.red instead of just red).
• Incorrect input types: Using outdated or incorrect input types, such as resolution instead of input.resolution in v4+, can cause undeclared identifier errors.
• Copying code from older versions: Scripts written for Pine Script v3 or earlier may use identifiers that no longer exist or have been renamed in newer versions.
