Hi @alojzy231
In this case using the manualColumnMove plugin and setting it the way you did happens before the Formulas plugin gets the access to the rearranged data which results in the error you get.
Instead, you can use the moveColumn method of the manualColumnMove plugin directly so the data is registered and the Formulas plugin can rearrange the formula underneath. Here’s an example: https://jsfiddle.net/handsoncode/0ecwq2kx/
