zabbix item deoendent on another item

[aream2000]

what im trying to do is get a zabbix item to only appear if another item for the same host is a certain value is this possible

[aream2000]

this is the calculated item i have setup

if(last("eco.mode",0),"eco.thermostatHeatSetpoint0 "), else(60)

i do have a item in the same host called eco.mode and it reports either a 0, 1 or 2
