In my survey have 2 Awareness question and only array question .
Q1 & Q2 are my awareness questions and Q3 is Number array which multi answer brands.Condition is If some one selected Q1 OR Q2 brands want to display only that brand in Q3 column rest all should hide .
Hi,
first: Are the brands in Q1 andQ2 the same?
Not so clear as you did not set an array exclusion filter.
Now, to do this you can use the plugin "hideEmptyColumn".
Your installation is hosted at LimeSurvey GmbH. So you are not allowed to install plugins. (LimeSurvey GmbH will do this for a little fee; read the website)
But fortunately the plugin is relatively easy. You can insert it directly into your question text.
