Unwanted update to parameter
Hi, here's my file:
I've tried out a bunch of different ways to approach this, each time it is working fine on my imac (5.0.536.0-d, 1 May 2019)
However, on line when I enter the first function correctly, it will match the curve as required but then mysteriously updateconstruction just on the parameter 'a' and not on 'd' and so the input is no longer correct.
After the first entry, it seems to work smoothly.
