I assume that you are using an expression for the value to Select in a Field. Create a text box and use your expression as a Measure so that you can see exactly what it returns to see if that gives you any hints as to what could be going wrong. Perhaps your value doesn't match the format of the field you are trying to assign to.
Hi @Arvind_07 - please send us a note at email@example.com . We'd be happy to show you how to stack Actions either with a Vizlib Button or use sheet actions with the Vizlib Sheet Menu. There are a few options that can help out.
You can stack as many actions (including waiting time) with Vizlib Actions for Qlik Sense in a variety of objects and visualizations.
