refresh data from web services

Hello,

I've defined 2 web services connection:

1.- Insert data from a cell to a table.

2.- Read data from a table to a cell.

I've defined a connection referesh button with those connections; and i would like than when i click this button, first it writes the value from a cell to a table and read this new value inmediately to displaying this new value in a graph.

It doesnt work ok, sometimes i need click the button twice or sometimes it works if i maintain pushed button for a seconds.

Do you know how could i do for executing that two sevices in a one click button?.

Thanks
