[fansanelli]

Hello,

can you please check the problems below?

PHP Notice: Only variables should be assigned by reference in vendor/easyise/eisexlsx/eiseXLSX.php on line 229
PHP Notice: Only variables should be assigned by reference in vendor/easyise/eisexlsx/eiseXLSX.php on line 205

PHP Warning: count(): Parameter must be an array or an object that implements Countable in easyise/eisexlsx/eiseXLSX.php on line 1159

I have a lot of these while writing with $xslx->data()
Thanks

Notices shouldn't be a problem. A warning is also not critical, but someonne should look over it I think...
