Cannot assign True

Question

I am using Math.floor in the Exit action of a field ((headwaterExistingMain10 is the field name) and this is the formula in Calculate action:

if (headFtExistingMain10.rawValue==null)
this.rawValue==null
else this.rawValue = (Math.round(hweFtMain10.rawValue*10)/10)+(Math.round(headFtExistingMain10.rawValue*10)/10)

and though the calculations work I'm getting this error message

"illegal value: cannot assign 'True' to xfa[0].form[0].form1[0].page1[0].table1[0].row5[0].headwaterExistingMain10[0].#value[0].#float[0]."

Thank you Kosta. Being a novice I'm not sure where the "true" is defined in my formula....

if (headFtExistingMain10.rawValue==null)
this.rawValue==null
else this.rawValue = (Math.round(hweFtMain10.rawValue*10)/10)+(Math.round(headFtExistingMain10.rawValue*10)/10)

Hi @reluctantprogrammer ,

hence your name 🙂

I think the offender is the this.rawValue==null == is a comparator not an assignment. Here my guess at what you wanted to do:
if (headFtExistingMain10.rawValue == null) {
this.rawValue = null
} else {
this.rawValue = (Math.round(hweFtMain10.rawValue*10)/10)+(Math.round(headFtExistingMain10.rawValue*10)/10)
}

I think if headFtExistingMain10 is null also set this field to null, correct? Try this and see if that fixes it.

@reluctantprogrammer Looks like a type mismatch between the object type and the value you are trying to set.

"illegal value: cannot assign 'True' to xfa[0].form[0].form1[0].page1[0].table1[0].row5[0].headwaterExistingMain10[0].#value[0].#float[0]."
