Values keep updating when changing one of the values

Thank you for responding.

If I understand correctly, I cannot use "event.value" if I want PRICE1 and PRICE2 to be independent ?

I also tried to use "this.getField("PRICE1").value=this.getField("PRICE1").value/1.2" but it only divides by 1.2 once and stops doing it when I type another number in PRICE1 field (PRICE2 still gets divided by 1.2) and when I change PRICE2, PRICE1 divides by 1.2

below is my calculation order

and here is my JS script :

//<AcroForm>
//<ACRO_source>PRICE1:Calculate</ACRO_source>
//<ACRO_script>
/*********** appartient à : AcroForm:PRICE1:Calculate ***********/
this.getField("PRICE1").value=event.value/1.2
//</ACRO_script>
//</AcroForm>

//<AcroForm>
//<ACRO_source>PRICE2:Calculate</ACRO_source>
//<ACRO_script>
/*********** appartient à : AcroForm:PRICE2:Calculate ***********/
event.value=event.value/1.2
//</ACRO_script>
//</AcroForm>

Is there a solution so PRICE1 and PRICE2 stay independent ?

Thank you
