I am new to learning apex code and have a scenario where we need to open a salesforce tabular report using the report’s name. I have created VF tab, visualforce page and kept the tab in homepage already. Below is what I tried in VisualForce Markup and a new page opens but doesn’t display the report. Could you please help me with what I could be missing. I appreciate it!

`<apex:page>

<script>
var reportName = "Employee Info";
var result = sforce.connection.query(
"SELECT ID "+
"FROM Report " + 
"WHERE Name = '" +reportName+ "' " +
"LIMIT 1"
);

var URL = '/'+result;
var win = window.open(URL,"target=_blank");
window.history.back();

</script>

</apex:page>`
