I'm doing a simple test for null in JavaScript of a lookup field. I'm getting an error every time.

Can someone tell me what my obvious error is?

Every time my error message is Cannot read property 'getValue' of null

        if (leadsource != null) {
           leadsource= fc.getAttribute("leadsource").getValue()[0].name;
       }

I've also tried

        if (leadsource != null || leadsource.length > 0) {
           leadsource= fc.getAttribute("leadsource").getValue()[0].name;
       }

and

        if (leadsource != null || leadsource.length > 0 || leadsource == undefined) {
           leadsource= fc.getAttribute("leadsource").getValue()[0].name;
       }

Thanks

Lee

Hello Lee,

Can you please provide the full code? Can you please confirm that field 'leadsource' is on the form? It seems that this leadsource field is out-of-box. What entity is it on?
