I'm going through LEAP training exercise 5 and I seem to be having trouble getting the expected results for the BAU scenario.

All my Current Accounts values closely match those provided by the the exercise save for Fuel Economy which is several order of magnitudes larger than the expected value.

I have extremely large negative future values as well, which does not make any sense.

Jwen Fai Low,

Can you please give me a little more information?

First of all, please tell me what version of LEAP you are using (check Help: About). Additionally, please let me know what values (including units) you are getting for fuel economy and what specific values you are getting for future values.

Thanks!

Tory

This seems related to a bug in version 85. Please update to the newest version (v.88) from within LEAP (Help: Check for Updates) or on COMMEND at LEAP: Download LEAP.

Please let me know if the problem persists in the new version.
