Please refer here for the Google Sheet.
I need to program a macro for the blue arrow at "Pill box visualiser" section such that when I click the button, a schedule is generated following the algorithm below:
All the cells from C4 downwards in the "Medication Record" tab will be scanned.
E.g. For "Medication Record"!C4, J4 = "on" (once every night) and L4 = "Y" (medication is taken regardless of whether patient has dialysis that day or not), all the cells from "Basic Info"!B50-H50 are added with a string of text combining "Medication Record"!C4, H4 and I4 --> "Calcium acetate 1 tab".
Next, for "Medication Record"!C5, J4 = "om" (once every morning" and L4 = "N" (medication is only taken when patient doesnt have dialysis on that day), "Basic Info"!B17-H17 will be scanned for the value "x". In this case, C17,E17,G17 and H17 do not have "x" i.e. no dialysis, hence C48, E48, G48 and H48 (Tues, Thurs, Sat and Sun morning) are added with a string of text combining "Medication Record"!C5, H5 and I5 --> "Bisoprolol 0.5 tab"
If J="bd", medications are added to "Morning" and "Evening".
If J="td", medicationd are added to "Morning", "Afternoon" and "Evening"
If J="od", medications are added to either "Morning" if morning slot has <5 names already, or "Evening" if morning slot has >= 5 names.
The values are added to the cell for subsequent medications, not replacing the previous entry.
I apologise for the long-winded explanation. Thank you very much for any advice!
