Extrapolation error Market Simulation

Hi,

I just succesfully run the Shares of Preferences analyses for my fixed-hold-out tasks. After that I was trying to run a Randomized first choice Market simulation, but I got the following errors on my Price attribute. ( In my research I made use of conditional pricing)

- When I select the price value  for example '2' (1 = low , 2 = medium 3= high). I get this error: Product # has an extrapolated value for attribute ' Price per packagetype'. Extrapolation is not permitted when running RFC.
- When I select the label for example 'medium' (high, medium, low) I get a different error, namely:
'Medium' is an invalid value for product #.

Could you please help me to find out why I got this errors?

Thanks!

Are you using the simulator within Lighthouse, or the standalone Choice Simualtor?  Also, what version are you using?
Or are you using the online simulator (https://www.sawtoothsimulator.com)?
Yes I use the  simulator within Lighthouse, version 9.5.3

This is a bug which has been fixed and will be shipped with v9.6, expected this week.

Okay thanks! So after this bug is beeing fixed I will be able to run this analysis?
Yes, but currently you should also be able to type the specific values for the conditional combination (instead of the 2 for medium) and it should work correctly.
