Steps to reproduce:

1.  Define 
   loadBalancerSourceRanges: in helm Chart
2. Deploy

Result:

**

Error: UPGRADE FAILED: template: zabbix-helm-chrt/templates/service.yaml:32:28: executing "zabbix-helm-chrt/templates/service.yaml" at <.Values.pushgateway.service.loadBalancerSourceRanges>: nil pointer evaluating interface {}.service

Expected:

in the template service.yaml, line 32,

.Values.pushgateway.service.loadBalancerSourceRanges

is used instead of

.Values.zabbixProxy.service.loadBalancerSourceRanges

So the helm installation is trying to use a non existent value... and then, not working ...
