Hello every one,  
I build the app related to nutritional status and I would like to calculate the nutritional status of user by using variable age, weight and height, for adult \> 19 yrs we use BMI which have forrmular (weigh / height2) but if it children \< 5 yrs we will using Z-score, it is possible to set the calculation to use difference formular in the same text input?  
I would like the output to show according to the BMI and Z-score result, Ex: if BMI \> 40 ==\> show the picture of obese and show the text obese, if BMI = 30.0-40.0 then show the result of overweigh picture and text overweight; if age \< 19 using another formula ; if age \< 5 yrs calculate Z-score ,…  
thank you in advance for all opinion and help

You can either use an [if/else block](https://www.youtube.com/watch?v=RAtGL5GUmj0) for this or you can use a [test block](https://docs.thunkable.com/control#test). Both can be found in the Control drawer.
