The error is self explanatory. The code assigns a decimal to a string variable.

Debug, find the error place. Use the toString() of the decimal value type or Convert.ToString() method before assign the decimal to string.

If you are not intended to use a string then use appropriate variable declaration.

Do you want someone here rewrite your code for a simple bug?
