synchronization between input and variable query

I create a table that received data by an input form and by another graph.

I need synchronize these: when I launch the model the table was launched with only variable input and only after a second was re-launched with variable and input.

Is possible synchronization all?

I try using the "timer connect", but the problem doesn't solve.

I think the correct way is using the "guard condition", but I don't understand how!

Any idea?

Thank you and best regards
