Layout Conditional - GetselectedCount

[#1]

I am trying to have a chart activate by a button right now. My button has selectinfield action for the field name Category, 'Supplies'. I want the chart to only show if Supplies is selected in current selections, which is what the button for.  I need to use GetSelectedCount(Category) > 0 and Category ='Office Supplies' somehow in the conditional.

=GetFieldSelections(Category) = 'Office Supplies'

if user can select more than 1 category you should use

substringcount(getfieldselections(Category),'Office Supplies')=1
