Hello Dragan

First thanks for your reply.

I don´t know these commands :
ARCC(),
and .BRCC(),
Could you describe an example?

When you say "The .controlSource is the qualified name of the field, i.e. "Bi.Article", not the actual text inside the field.", can i create a simple code like the same i send , but for display actual text inside the field.

I need to run the procedure only for changes on the column.controlsource BI.Article, do i need a cycle FOR...ENDFOR.

Best regards,
Luis Santos
