Steps to reproduce:

1. Created an LLD rule
2. Created a trigger prototype ()
3. Created a prototype char

Result:

1. If I use "{#MAXCHANNEL} * 0.9" in the trigger expression
ex.: {Template App IBM MQ ver.9:qm.connection[QMConnects,

{#QMNAME}].avg(#3)}>={#MAXCHANNEL}*0.9, 

that the trigger is not displayed on the chart


2. If I use {#MAXCHANNEL} in the trigger expression:
ex.: {Template App IBM MQ ver.9:qm.connection[QMConnects,{#QMNAME}

].avg(#3)}>={#MAXCHANNEL}, that the trigger is displayed on the chart

Expected:
1. If I use "{#MAXCHANNEL} * 0.9" in the trigger expression
ex.: {Template App IBM MQ ver.9:qm.connection[QMConnects,

{#QMNAME}

].avg(#3)}>={#MAXCHANNEL}*0.9, 

that the trigger is displayed on the chart
