Math In Cells

Hi!



I’m trying to get a cell to calculate from the values of the two preceding cells. I can only get the formula “ro[=c3c4]" itself to show in the cell. Preceding that I get and error: “Error type: Configuration Description: Incorrect cell type: math”.



I have also tried to configure the cell formula as "ro[=4
5]”.



Just in case this matters, the data is injected into a new row created with the addrow() function.



Any help would be much appreciated.

To use such expresion you should include dhtmlxgrid_math.js" file to your page (availible at PRO version only).
