Error in the trigger expression of price or amount

Hello, I have this trigger that I changed. Before it put a Dutching Lay on 2 selections and I modified to put 2 simple lay bet on those selections but now gives me these error "Error in the trigger expression of price or amount....."

I have a variable that contains the value I want to bet (liab_size).... What is wrong with this?

Thank you for your attention.

Hi
In the settings on the logger tab, if you tick log trigger expressions, you will get detailed information in the log about variables, calculations etc. which should help you to find the problem. If you still have a problem then if you attach the trigger file I will have a look.

Thanks MarkV.... I see where I was wrong....

When I changed to a simple lay bet instead a dutching bet, in the price I have 0.... Change to back_price and worked....

A noobie error....

Thanks
