Hello Ben,<br>
<br>
Thanks for such a quick reply!<br>
<br>
It should become something like that indeed!<br>
<br>
But... correct me if I am wrong (I am at home now so no e-prime at my<br>
disposal, i'll certainly give it a try tomorrow), it seems that in the<br>
code you wrote the 'second m' is placed outside the attributename<br>
whereas I actually need it to be inside the attribute name, to adress<br>
attributes called "restid1", "restid2" and "restid3" .<br>
<br>
And (but thats secondary at the moment) it should be a variable other<br>
than m as m will run up till 16, whereas this piece of code should be<br>
repeated every 4 lines of m.<br>
