access vba - What's wrong with my VBA code (I'm getting runtime error 9) -


i've looked around , found "runtime error 9 subscript out of range" error has arrays. however, i'm not sure how interpret answers i've found best suite code.

i have simple function wrote pull first , last names out of field, found field had few nulls in , tried compensate changing string variant decleration.

i've gotten work without error similar code... not code.

my code follows:

    function flastname(byval lnin variant) variant     dim astrfullname() string     if isnull(lnin)         flastname = null     else         redim astrfullname(2) 'this new concept me... not sure if need         astrfullname = split(lnin, ",")         flastname = astrfullname(0)      end if end function

thanks in advance insights , assistance.

edit: found issue array doesn't null value in of name fields... thought following line fix that:

if isnull(lnin)     flastname = null

but apparently wrong.
have advice on i've found far?

you dont need redim ... , dont have dim array.

function flastname(byval lnin variant) variant     dim astrfullname     if isnull(lnin)         flastname = null     else         astrfullname = split(lnin, ",")         flastname = astrfullname(0)     end if end function

ps: assuming lnin contain comma separated string ... else may have put check.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
