Part L Compliance Report Not Generating

Hello,

I have a project where the Part L Compliance Report is not generating and I cannot figure out why.

I've tried the suggestions on other forum threads but I haven't had any joy.

The Energy Report generates each time but the Compliance Report option is grayed out:

4024 MacDuff Key Depot 19.12.16.zip

Could you have a look at my data file and shed any light on my issue?

Many thanks,

Ross
