Hi
Are you meaning the last matched lay bet price?
and selections trigger expression bm_layp is between range1 and range2
range1 must be less than range2
edit: looking at your trigger, I don't think you can use decimal in a constant name. From the manual:
"The allowed symbols for the name of a variable are:
- Latin letters A-Z, a-z. Example: Myvar
- Figures 0-9. Example: point1
- Space, underscore. Example: one_plus_2
"
