I've used #if with #arraymap in wiki of the 90th. Have a look at it here [1]

{{#if: {{{Source|}}}|
{{!}} '''Источник''' {{!}}{{!}} {{#arraymap:{{{Source|}}}|;|x|[[Source::x]]}}|}}

Hi all

I have the string

| '''language"
| {{#arraymap:{{{language|}}}|,|x|[[language::x]]}}

and I want it to be shown only if a text is entered, and to be hidden when
it's null. I guess I should use the parser "#if", but how exactly do I write
the parser so it would work?
I've tried all kinds of grammar, but none worked.

Help please!

Thanx in advance,
