Javascript execution delay

I have columns of checkboxes with 2 textboxes below each of them. 1 textbox sums the values of the checkboxes. The following script is in the 'custom calculation script' for the 2nd textbox and based on the CB sums(BasicTotalLodge01), the text in the other textbox changes:

if (this.getField("BasicTotalLodge01").value < 6) {
event.value = " Still Working"
}
else {
event.value = "Lodge 1 Complete"
}

The script works as planned in the Lodge01 column. Toggling a CB changes it back and forth successfully. However, when testing Lodge02, 03, 04, etc, the text does not change until any other cb is changed.

I hope i worded all this in a way to understand.

As always, help is appreciated.
