Hey guys,

I am needing a script that will make a field equal 0.00 if there is no input. If there is input, then it no longer equals 0.00 and is whatever they type in. I can’t figure it out. Here is what I’ve tried, but none of it works——

[CODE]
var a = this.getField(“LO”);
if(a == “”)
event.value = 0.00
else if(a == //* this is where I don’t know what to put
[/CODE]

and then I’ve tried this——

[CODE]
var a = this.getField(“LO”);
if(a==””) {a = 0;}
[/CODE]

Any help would be appreciated! Thanks guys

@KorNov 02.2007 — What is [B]a[/B]? A value? An object?

@dnormanauthorNov 02.2007 — the "a" is the variable for the field name ("LO") i am needing validated, i guess you could say. If it helps any, it is for a pdf I am using in Acrobat Pro 6. I work for an insurance company and there is a form our agents use to calculate premiums and with the calculation script i am using, if a field is blank, then the script doesn't work. And not all of our agents know much about computers so I want the field to be filled in with a 0.00 automatically if they do not put any information in. (because the fields are optional and might not have any input). The script cant have any html tags or anything, just simple regexp's. Thanks guys ?
