What causes it

The whole-number input is input.int(). input.integer was the v4 type constant (input(14, type = input.integer)), never a function.

The fix, compiled

Write input.int(); input.float(), input.bool(), input.string() and input.source() follow the same pattern.

Prints the error at line 3

//@version=6
indicator("My script")
len = input.integer(14, "Length")
plot(ta.sma(close, len))

Compiles with no error

//@version=6
indicator("My script")
len = input.int(14, "Length")
plot(ta.sma(close, len))

Names Pine cannot find

Compiled on TradingView 23 October 2026. The checker above reads repaint and v6 migration patterns; TradingView's compiler is the final word on whether a script compiles.

Method and privacy

Method: The script loaded in the checker was compiled on TradingView's Pine compiler on 23 October 2026 as //@version=6, and printed this error at line 3; the fix below compiled with no error or warning. Names such as variables come from the example and will differ in your script.
