we have the same problem.
In dependence of a variable vCurrency we want to change the result column from € to £ values via a currency button. This works fine in QV. In NPrinting we have the result after the reload and nothing changes in the NPrinting report after clicking on the currency button. The variable value remains on the same value after reload.
We use 17.3.
Do we something wrong? When not will this problem be fixed in June or September 2017 version?
Thanks for Information.
