Measure  = CALCULATE(view[c],ISBLANK(view[CS]= FALSE()))

the view[c] is another meaure which works on its own

view[CS] column return blank without error

but when I apply the above meaure " Measure  = CALCULATE(view[c],ISBLANK(view[CS]= FALSE())) " it throighs an error

"MDXScript(model) (12,118) calculation error in meaure :DAX comparisons do not support comparing value of type text with values of type true/false . consider using the value or formate function to convert one of the values,

but I am not sure of syntax , could you help please?
