WFRP4e Help needed: Inline rolls not displaying when using the {template:wfrp}

I'm wondering if you can help? - I've been working on a few template based table automations, macros and some in-line rolls for my game in WFRP4e. I have the official sheet and compendium etc. Frustratingly if I write a macro script with the {template:defalut} on - they work perfectly, however whenever I change the template to {template:wfrp} the macro runs (and the animated dice roll) but when the box appears in the chat it doesn't display the results of  the dice rolled....  Can anyone help?  - (image shows the table roll, then the failed attempt to use the wfrp template and then then successful attempt to use the default.) I would expect the following script :  &{template:wfrp}{{name=Fumble}}{{roll=[[1d100]]}}{{roll_name=Oops table}} {{roll_type=Critical fumble}} to deliver a D100 roll but when tested this simple script only returns this in the chat: if anyone can assist I would appreciate it as I've not had any help on my original post and R20 have pointed me back here to the forum.

I'm not familiar with the WFRP sheet, but the thing I would check is if it accepts roll as a key (in {{roll=[[1d100]]}} For some templates, the keys have to match exactly what the template is expecting, or they won't be displayed at all. There's probably a guide to that rolltemplate on the wiki page for the sheet.

thanks @Gigs - Honestly I wasn't aware there was a wiki for the char sheet so ill have a search around and see if I can locate it. Cheers.
