Workflow Soluiton

So we have a webform that has a few check boxes on it.  I want to be able to hide a few of them based on some pre-determined info. So our users will enter a search item and the result could be A.B,C or D.  If the result is A or C I want to hide a check box if it is B or D the check box can stay.

So I went to the visability setting on the check box and selected dynamic model.  Now I assume the dynamic model just needs to output a true or false and that will hide the box or not hide it. So inside my Dynamic model I have a matches rule to compare A or C. Now How do I make those enter a true on the end result or a false on no match.

I thought I could just use a merge text and have one be true and one be false but that when I go to the end component and search for the result it doesn't show the merge text fields as selectable.

So I am not sure what to do from here.

Any help would be great. 

Thanks in advance.

I found it, Digging through some old threads I was able to find that using two end components I was able to accomplish what I needed.

Use the visability dynamic model, Add the variable to check then on the true side add an end component  in the result select create value and select the value check box. This will give you the true side. On the other side select create value but leave the Value box unchecked this will give you your false.
