I need to figure out when to restart a loop so I need to do this

<code>
{$ItemOrderby = 100}
{if $p.orderby gte "100" }
{$idiff = $ItemOrderby - $p.orderby }
IDIFF = {$idiff} <!-- just printing it out - it's alway blank ...
Difference = ITEM {$ItemOrderby} less current {$p.orderby} = {$idiff}

{if $idiff gte "100" }
</ul>
{$ItemOrderby = $p.orderby}
{/if}

</code>

but anyway - it's not doing the subtraction ... I found an old post from 2008 that said use {math}

but that it's slow ... and also 2008 was ages ago

what is the best way to do this now ?

thanks

Have you tried {if $p.orderby gte 100 }
(Without the quotes)

That part works

It's just that if the difference is greater than 100 (inother words we're in the 200 series) then I want to close the <ul> and start a new one

so in pseudo code

if (idiff gt 100) </ul><ul><li>


but I diff is coming up blank - not zero - just blank

I found this

{math assign="amount_to_go" equation="max(0,49-a)" a=$cart.subtotal}

so I'm going to try a variation on that

Again if you trying to perform a comparison with integers then don't put quotes around them.

OK I did that

but i can tell by write statements that it goes into the if block but inside these lines

{$idiff = $ItemOrderby - $p.orderby }
IDIFF = {$idiff}


I try to print using IDIFF= {$idiff} and it prints nothing - not a zero - just blank

so it's not doing the math

Oh, you are trying to assign a variable I believe.
Try just using {$ItemOrderby - $p.orderby} that should print the value you are looking for essentially doing the math and rendering the result.

If you need to assign the result to a new variable:
{assign var=running_total value=$running_total+$some_array[$row].some_value}

I got this to work by doing the math in the assign

{assign var='iprev' value='100'}

{foreach from=$pages_menu item=p name=page}
{if $p.orderby gte 100 }
{assign var='idiff' value=$p.orderby - $iprev}

....
{assign var='iprev' value='200'}

etc.

thanks for pointing me in the right direction !
