Help with a condition adding a value when is not present

[neby]

Hello, i got the next formula,  

If(ISBLANK("Folio"), [Precio] * [KG], ([Precio] * [KG] * 0.19) + [KG] * [PRECIO]) 

And is adding that 0.19 where it doesnt belong. In the first row giving that  Blank "Folio"  it should multiply it straight, but in the result adds that 0.19 anyway. 

The second row is exactly the result i expected.

I think you want the following expression

If(ISBLANK([Folio]), [Precio] * [KG], ([Precio] * [KG] * 0.19) + [KG] * [PRECIO])

It was the brackets! 😓
