Error Validation isn't working properly

If(

IsError(Set(newID, 1/0)),

Notify("Error"),

Notify("no error")

)

I was just checking the above condition thinking it would Notify("Error"), but the opposite happened and it notified "no error". What is the reason here? How can we fix this?

The reason you see 'no error' is that the Set function worked as it expected: it stored the <error> value into the variable 'newId'. Errors are values that can be stored (in memory, not in a connected data source) and handled later as part of the normal (non-erroneous) execution of the app.

For example, if we have a button with an expression 'Set(inverse, 1 / Value(TextInput1.Text))', this operation will always work. If you have a label with the expression 'If( IsError( inverse ), "The inverse is an error", "The inverse is " & inverse )'

Hope this helps!

After you run the code, technically the code run without an error and you did set the value of your variable, the only issue is that value will be of type ‘error’, thats why you have false result of iferror.

Thats my understanding at least.
