Below is the ss

@Seema_Jethe

you can write as gstcertificates <> ""

If that is string that is enough

Hope this will help you

Hi @Seema_Jethe

Another alternate way is

Yourvar IsNot Nothing

@pravin_calvin ok

You have a few options to do that.
If your variaable is of type String, i suggest you to user

not String.IsNullOrEmpty(gstcertificate)

Is your variable is of another type:

gstcertificate IsNot Nothing

User String.isnullorempty(your_varaible) :slight_smile:
