hi  
I am new at robot framework  
I want fetch value from UI and after that performed the addition operation on that two value  
result i get that two value like [‘703\nDC’] + [‘4773\nMC’]  
fetch value like 703\nDC  
second one 4773\nMC

```
@{element} = Get Items List ${loc_mc_dc}
@{CountList} = Create List
@{CountList1} = Create List
Append To List ${CountList} ${element}[0]
Append To List ${CountList1} ${element}[1]
${num1}= Set Variable ${CountList}
${num2}= Set Variable ${CountList1}
${mysum}= Set Variable ${CountList} + ${CountList1}
Log To Console ${mysum}

```

Here is my answer based on your example:

```python
***Test Cases***
Sum Two Numbers
    ${num1}= Set Variable 703\nDC
    ${num1}= Convert To Integer ${num1.split()[0]}
    ${num2}= Set Variable 4773\nMC
    ${num2}= Convert To Integer ${num2.split()[0]}
    ${mysum}= Set Variable ${num1} + ${num2}
    Log To Console This is not the expected result: ${mysum}
    ${mysum}= Set Variable ${${num1}+${num2}}
    Log To Console This is a possible way to get the expected result: ${mysum}
    ${mysum}= Evaluate ${num1} + ${num2}
    Log To Console This is another possible way to get the expected result: ${mysum}\nMy preferred way :).

```

Thanks  
${num1}= Set Variable 703\nDC  
${num1}= Convert To Integer ${num1.split()[0]}  
${num2}= Set Variable 4773\nMC  
${num2}= Convert To Integer ${num2.split()[0]}  
${mysum}= Set Variable ${num1} + ${num2}  
${mysum}= Set Variable ${${num1}+${num2}}  
Log To Console This is a possible way to get the expected result: ${mysum}

after that i get result like that  
Resolving variable ‘${[‘703’]+[‘4773’]}’ failed: Variable ‘${[}’ not found.

and after used ${mysum} = Set Variable ${num1}+${num2}  
result is .[‘703’]+[‘4773’] only number

I also try with these one  
${mysum} = Evaluate ${num1} + ${num2}  
result is .[‘703’, ‘4773’]

My example was a fully working example. You need to adjust yours, to use the elements correctly.

When you see `${[‘703’]+[‘4773’]}`, this means you did not get the first elements of the lists, before converting to integer. If you have a list `mylist=[‘703’]` you need to get its first element, for example: `${mynum}= Convert To Integer ${mylist[0]}`.
