Calculations - how best to approach this in Storyline
I am struggling to resolve a problem. I want to create a calculator but cannot work out how to increase the total if the same button is pressed more than once. For example if I press 1 the total will be 1, but if I press 1 a second time I will want the result 11.
I have tried changing states firstly to 'selected' (on the first click) and then to 'x10' on the second click to adjust a 'quantity variable' but this doesn't seem to work despite trying different order sequences.
Is there any willing to provide advice ... I hope so!!
