Hi!

Thanks for your quick response, I've seen the solution, but I don't know how to apply it to my case for the Xmin and max values, Ymin and max values; Can you help me to settle this please.

Thanking you in advance.

You need to go into the TableAdder custom transformer by right clicking and choosing Edit

Then find the TextBoxAdder_3

in the Min Y value box of this transformer copy and paste

$(MAXYVALATTR)-$(HEIGHT)*2-2*$(HEIGHT_2)*@floor((@Value(_count)/(@Value(AttributeCount))+2))

In the Max X value box copy and paste

$(MAXYVALATTR)-$(HEIGHT)*2-2*$(HEIGHT_2)*@floor((@Value(_count)/@Value(AttributeCount)+1))

Thank you very much, it works ! :)
