trying to add multiple results from while loop

[thebighere]

hey,

I am stumped and I may be just missing a basic element of php or mysql, but I don't think so.

I am using a while loop to return a dollar amount which is the total(sum) of X other dollar amounts which are the results of a different while loop.

basically:

while (x) {
1 $1
2 $2
3 $3
while (y) {
subtotal: $6
}
}
while (x) {
2 $3
4 $5
while (y) {
subtotal: $8
}
}

// etc.

This is working fine.

My trouble is, how do I add the sums of the subtotals?

Hopefully that makes sense.

Thanks in advance.

while (x) {
1 $1
2 $2
3 $3
while (y) {
totaltotal=totaltotal+subtotal;
subtotal: $6
}
}
while (x) {
2 $3
4 $5
while (y) {
totaltotal=totaltotal+subtotal;
subtotal: $8
}
}
totaltotal=$14
