Pre selecting check box if previous condition match

I need to preselect the check box if the condition matched with the previous answer. For example if :

M1_r9_c1=1 then MTFS1_r9_c1 should be preselected.

I don't much understand Java Script but from this forum I came to know we can do it using Java for example to preselect  a radio button we can use the given below script:

<script type="text/javascript">
  SSI_SetSelect("grid1_r1_c1", true);

However, in my case I have to implement it based on previous answer and on check box rather than radio button.

Please help.

You can use the SSI_SetSelect function which will tick the check box and update the data file accordingly.

In the 2 examples below, the Q2 code 10 check box will be ticked as you submit Q2 and the data will become a "1" for the  Q2_10 variable.

Example 1 (sample field condition)
if ("[%Firm%]"=="Acme")
 SSI_SetSelect("Q2_10", true);

Example 2 (survey question condition)
if ("[%Q1%]"=="1")
 SSI_SetSelect("Q2_10", true);

Pop your script into the custom JavaScript verification tab window which is found by clicking on the advanced button of your question (in this example Q2).
