Trouble with Checkbox mouse-up script to spawn/delete pages

[Kemper5F9B]

I have a mouse-up javascript containing a doc-level function name, when selected spawns 5pp. When unselected the spawned pp don't delete. I've re-written the doc-level function script, assigned unique fields names across the 5 spawned pages, and re-created the templates, all following suggestions I found here in the Community. The Console also displays no errors. Here's the doc-level script I'm using.

function calcP19Marker()

{

var P19 = getSpawnedPageNumber(this, "P19Marker");

if (this.getField("CkBxNMVTIS").valueAsString=="Yes" ) {

if (P19==-1) {

this.calculate = false;

this.getTemplate("p19").spawn(this.numPages, false, false);

this.getTemplate("p20").spawn(this.numPages, false, false);

this.getTemplate("p21").spawn(this.numPages, false, false);

this.getTemplate("p22").spawn(this.numPages, false, false);

this.getTemplate("p23").spawn(this.numPages, false, false);

this.calculate = true;

}

} else if (P19!=-1) this.deletePages(P19, P19+4);

}

Field "P19Marker" is used to ID the Starting page. The remaining 4 pp also contain their own unique 'Marker' fields.

Any help as to why the pages spawn on checkbox selection but do not delete when unselected is greatly appreciated- thanks in advance!

Any error message in the Javascript console?

none

Yes I think so. This comes up when I select a checkbox to show a field with a custom calculation script.

if (this.getField("SellPrice").value!= "0.00") {

var owedTaxAmount = (this.getField("SellPrice").value - this.getField("TradeInValue").value)

var resCounty = (this.getField("CountyTaxRate").value);

if (owedTaxAmount < 5000.01) {

event.value = owedTaxAmount * (0.06 + resCounty);

} else if (owedTaxAmount > 5000) {

event.value = (((owedTaxAmount - 5000) * 0.06)) + (5000 * (0.06 + resCounty));

} else {

event.value = 0;

}

}

It executes fine though. But the message says "Unable to find format" at the bottom of the Console?  "CountyTaxRate", "SellPrice", and  "TradeInValue" are formatted for Number with decimal. "CountyTaxRate" has 3 decimals, and both "SellPrice", and  "TradeInValue" each have 2 decimal places. Both "SellPrice", and  "TradeInValue" also have default values of "0.00". How would this be affecting my other checkbox problem?? Thanks in advance for any guidance!
