Calculating differences

[Peter Almond]

Kia ora kotou

Oxcal doesn't like this line in my script:

Difference("BB_present_II_interval", C_Date(2001), "BBE_II") where BBE_II is a parameter derived from the model.

Is a cross-reference the solution here?

Thanks

Peter

Yes, you need

Difference("BB_present_II_interval", C_Date(2001), "=BBE_II")

 

Best wishes

Andrew

Thanks Andrew

I did as you suggested but still no go. When I comment out the line the script runs, when I turn it back into a line of script I get errors with resolving order.

I figured out a work-around. I defined a parameter

Now=C_Date(2001)

Then

Difference("BB_present_II_interval", "Now", "BBE_II")

worked. Note I didn't use the cross-reference format for the parameter BBE_II.
