Higgs self coupling program trilinear-FF issues

Hi,

I am trying to compile and test the trilinear-FF program for calculating Higgs self-coupling via one-loop effects. This program directory is on the madgraph website at:

https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/HiggsSelfCoupling

I have followed the instructions in the ReadMe.txt file in the directory which explains how to link with LoopTools, etc.

However I am currently stuck on the last benchmarking step for ZH as when I run madgraph the function HZZ_0.f doesnt find two coefficients 'hvvcoef1_' and 'hvvcoef2_'. Full error below. Does anyone have any insight as to why this is happening ? For example does the code only work with a particular version of madgraph (MG5_aMC_v2_5_5) ?

Cheers
Roy

The following switches determine which programs are run:
/=================== Description ===================|============= values ==============|======== other options ========\
| 1. Choose the shower/hadronization program | shower = Not Avail. | Please install module |
| 2. Choose the detector simulation program | detector = Not Avail. | Please install module |
| 3. Choose an analysis package (plot/convert) | analysis = Not Avail. | Please install module |
| 4. Decay onshell particles | madspin = OFF | ON|onshell |
| 5. Add weights to events for new hypp. | reweight = Not Avail. | Please install module |
\=======================================================================================================================/
Either type the switch number (1 to 5) to change its setting,
Set any switch explicitly (e.g. type 'madspin=ON' at the prompt)
Type 'help' for the list of all valid option
Type '0', 'auto', 'done' or just press enter when you are done.[60s to answer]

Do you want to edit a card (press enter to bypass editing)?
/------------------------------------------------------------\

 you can also
   - enter the path to a valid card or banner.
   - use the 'set' command to modify a parameter directly.
     The set option works only for param_card and run_card.
     Type 'help set' for more information on this command.
   - call an external program (ASperGE/MadWidth/...).
