Hello everyone!! I am new working with nettalk...

I have a form created with Nettalk which contains 2 variables: LOC:Code and LOC:Description

LOC:Code is an input field where the user enters a product code and LOC:Description is a text where the description of the entered product is displayed.

Every time the user enters a code, the description is displayed and the code remains empty and focused again, waiting for another code to be entered.

I want that if after 10 seconds the user does not enter any other code, the description disappears.

For this I have created a NetWebSource procedure with a Timer, but I don't know where or how to tell it to clear the variable LOC:Description ?
