  • That's because myjavascript.js is sent as-is to the client and therefore asp.net never replaces the <% tag content. To make server-side data available to the client, you can either put it in an inline script or fetch() it from the client-side JS. The first way is very simple: insert <script>const theID = "<%=Me.lblfinalgrosstotal.ClientID%>";</script> above your existing script tag, then use theID in your script.
