No valid field Selected - Macro

[dkungu]

Hi

Help to fix this error, the macro is intended to select Y-target variables and X variables. Unfortunately I cannot attach a packaged workbook with html

Hi dkungu,

It would be easy if you had the macro attached to analyze the error, but if you are trying to select columns based on inputs ( I assume columns may vary and so the macro ) you can try with the below configuration as reference

is there a specific reason to select columns based on executing your expression by updating the XML? because if that's really required we can try to recreate that part with some other method.
