Blank initial decision inputs?

posted about 1 year ago Shayne Gary 12 posts	Apologies for what is probably a simple question, but I'm new to Simulate and haven't been able to find a solution to this in the help documents. I would like to have the text decision input boxes blank at time=0; but then retain the current input values (as they do currently) from time=1 onward. I don't want participants using the simulation to anchor on the model's initial values (at time=0), when they begin making their decisions - but we do want them to be able to see their own choices, after each decision (i.e. from time=1). Any suggestions would be appreciated.

Thanks! Billy

To use it check off the checkbox in the Decision Input settings called "Initialize with blank value" Best, Billy

posted 12 months ago Shayne Gary 12 posts	Hi Billy, A quick question re this new functionality please - I have conditional formatting on these decision inputs (e.g. a value between 0 and 100 must be entered, before participants can run the simulation). With the "Initialize with blank value" box ticked though, Forio is still recognizing the values stored in Vensim for this decision input (e.g. 50). As such, participants can click "run" when the decision inputs are blank and the simulation will run successfully (i.e. the conditional formatting error message fails to appear). I can change the initial values in Vensim, so they are out of the conditional formatting range. But before I change the model, I'd appreciate if you would let me know if there's a simple way to stop this from happening in Forio - that is, if participants don't enter a value in the blank decision input box at t=0, is there a type of conditional formatting that will stop the simulation running? Thanks in advance, Shayne
