Hi.

I have two values and I want to add them together and apply a percentage increase to them, but with the command I’m using, it’s only applying the percentage increase to the second value, not the sum of the two.

I use a Spanish configured version of Calc, so here’s the command that I use:

`=suma(X+Y/100*Z)`

(where *X* and *Y* are the two cells that I wish to add together and *Z* is the percentage as recorded in another sell).

Using this command, Calc is adding 20% to Y then adding the total of that to X. What I want it to do is add X and Y together then increase their total value by 20%.

Thanks in advance.
