Hi thanks for your answer. First of al you mean that the code we used: price.price_value+2 = price +tax
And that price_value = the price without taxes?
Second we did try to do different values before but everything after a point or a komma doesnt work. We can only enter 1 or 2 or 3 etc.
We did try it now again and when we enter for example:
price_value+0,47933884
(calculation we used: €3,00 - 2,42 = 0,58
0,58 : 121 = ... x 100= 0,47933884
then this happends: tabel price_value, doesnt excist
when we use price.price_value+0,47933884
This happends: kolomn price_value, doesnt excist
When we use price.price_value+2
then this happends: It works and the price gets higher with 2,42
So why doenst it work after a komma for us? Something wrong in the system or are we doing something wrong?
