Hi can someone let me know if I am on the right track with this calculation

and also why I'm getting a "syntax error 4: at line 5"

var a = this.getField("Check_Box_1").value;
if(a == 1) 
//event.value = No_cards_in_pack_Row_1 * 0.35;  //  
else if (b < = 1)
var b = this.getField("more_than_1_pack_state_quantity_Row_1").value; //
event.value = pack_price_10_per_cent_off_2_or_more_Row_1 * b;//

With Thanks

White space can be used to separate objects, and operands and not let JavaScirpt try to make the decision. So one should not place spaces or blanks within the string for an operator.

The less than or equal operator is '<=' and not '< ='.
var a = this.getField("Check_Box_1").value;if(a == 1)//event.value = No_cards_in_pack_Row_1 * 0.35;  else if (b <= 1)var b = this.getField("more_than_1_pack_state_quantity_Row_1").value;event.value = pack_price_10_per_cent_off_2_or_more_Row_1 * b;

The '//' string is the value used to mark the start of a single line comment. The ';' is the JavaScript line terminator. There is also a pair of marks for marking multiple line comments.

You should also remove the // before the beginning of line 3. It causes an illegal if statement.

In running your code I have found that you have not defined a number of variables or you are not accessing the field object for the named fields, 'No_cards_in_pack_Row_1' and 'pack_price_10_per_cent_off_2_or_more_Row_1'.

Also what is the value of 'Check_Box_1' when checked?

Also, you're trying to check the value of b before defining it.
Bottom line, this code has more errors than correct lines...

Already removed //

The check box value is 1 which = a variable amount of cards * 0.35

Once more than 1 pack is ordered then 1st pack and 2nd pack also becomes minus 10%

yes I'm not accessing the field object for the named fields agreed

"No_cards_in_pack_Row_1" is where amount of cards is typed in

"pack_price_10_per_cent_off_2_or_more_Row_1" is the total minus 10%

thanks
