i dont know if it the code i have already thats causing the problem or the fact that i dont know how to do MOD properly.. :(

its causing bad gray hair.. :(

so if anyone else is able to point out how to correct the code.. it would be of great thanks... :)

i have included the whole asp page as to show you the whole script incase i missed something or something needs to be added to make it work.... thank you..

im trying to get the record from the DB to display 3 times on the row before going down to the next row..

HOPE someone can help and point me in the right direction...

thanks in advance.. :)

The result of the MOD function is the remainder, as a whole integer that remains after the division takes place. Some simple examples:

1 MOD 3 = 2
2 MOD 3 = 1
3 MOD 3 = 0
4 MOD 3 = 1
5 MOD 3 = 2
6 MOD 3 = 0

The important point to note here is that if you test for the MOD function to = 0 then that will return true at every instance where the lead integer is completely divisible by the divisor, in this case 3. So, a very simple change is needed in your code, to change the MOD test from 1 to 0.

If x MOD iCellsPerRow = 0 Then
