Hi there,

I'm a new user of limesurvey and setting up a first online survey - very happy with the content so far, and have made good use of the suggestions in the forum and the manual.

I am trying to validate a multiple numeric question. The first question asks:
'How many total children do you care for'
the second asks:
'How many of these children need additional assistance'

each of these questions are asked of different age bands.

I am wanting to make sure that the answer to the second question is not greater than the first.

To do this, I have set up a Custom_On_Load function (using the workaround section from the manual), and I have it working as long as a numeric value greater than 0 (zero) is entered. If 0 (zero) is entered, it seems to store this value as 'No answer' - i.e. as a string.

Is there a way to store 0 (zero) as the actual number 0 instead of the string?

There may be a workaround with javascript here - my js is a little sketchy. I can use the INSERTANS reference as long as it is either a number or a string, but cannot reference both in the same code.

I have tried to use Multiple short text using the numbers_only too, but seems to get the same result.

Thanks for the help here – I am using version 1.72 (5737).

I think at the latest 1.80 RC2 which will be released in about a week numerical input is stored as floating point numbers if this helps you.

Otherwise you have to improve your JS skills

Thanks for the quick reply Mazi

Is there a way to store 0 (zero) in a multiple numeric type question as the number zero, instead of 'No answer'??

Not an easy one. You'll have to modify the source code. Better wait for LS1.80 RC2 and check if these answers are treated different there.
