CAML Query on list view with Control Value as parameter

Hi,

I am trying to filter my list view with multiple conditions. At the moment, using Item Property field name yields no results. Hardcoding the field value works fine though. 

No result -> <Eq><FieldRef Name='LinkedId'/><Value Type='Number'>ExposedEctId</Value></Eq>

Expected result -><Eq><FieldRefName='LinkedId'/><ValueType='Number'>78</Value></Eq>

How do I use field name to get the expected results.

Thanks!
