Hi. I suddenly got this message “The operation yail-divide cannot accept the arguments: , [empty-string], [120]” after I change background colour for “total_formula”. Before this, it works well. Please help. Thanks.
there is no enough information in your query. please explain properly…
This app is for calculating how much dose for u to take based on your weight (kids only)
- Spinner1 (option to choose 3 types of paracetamol, each types have different calculation)
- berat_badan (body weight (less than 50kg only))
- padam (clear)
- Kira (calculate)
- keputusan (answer), if choose 120mg/5ml paracetamol :
formula: 15mg/kg of paracetamol,
so,
15mg x “body weight, (eg: 10kg)” = 150mg,
then,
150/120 x 5ml = 6.25ml
if choose 250mg/5ml paracetamol :
formula: 15mg/kg of paracetamol,
so,
15mg x “body weight, (eg: 10kg)” = 150mg,
then,
150/250 x 5ml = 6.25ml (6.25 is the answer “keputusan”)
- berat_badan (body weight)
- 15mg x “berat_badan” (The answer is 150mg paracetamol)
- 150mg paracetamol (based on answer from no.7)
- if choose 250mg/5ml paracetamol, so “250” will show up
- “keputusan” (answer)
Maybe besides bgcolor, you accidentally changed something else? Did you change it from designer’s properties or from blocks ?
I just replied
I didn’t realize if I have changed something. I changed it from Designer’s properties
Can you try changing this block to any math number block
I don’t understand. Can you show it to me? Sorry I’m a newbie
still same
Or temporarily when click set total_formula test to berat_pcm_formula2.text to see the result and check if it empty
it shows like this, so what should I do?

How do you calculate berat_pcm_formula2 ?
berat_pcm_formula2 is no.8 (duplicate from no.7) *see app screenshot above
So actually the problem is caused by berat_badan.text
So how to fix it?
@dora_paz Here is the aia file. Could u explore it and tell me the correction?
