Can you put code in alerts for app script

I’m new to app script and I was just wondering if there was a way to input a cell value into an alert.

I tried

var ui=SpreadsheetApp.getUi()
var winScreeen = ui.alert('Win:',sr.getRange('U5').getValue())

>Solution :

Instead of

var winScreeen = ui.alert('Win:',sr.getRange('U5').getValue())

use

var winScreeen = ui.alert('Win:' + sr.getRange('U5').getValue())

The above used + to concatenate two values.
