ANCHOR-BOTTOM PROBLEM -Cannot convert enum

[Reza nasimi]

Hi 
I was searching for the way of creating text object in chart and I find this page :

https://docs.mql4.com/constants/objectconstants/enum_anchorpoint

it seems to be exactly what I need .

in the same page there was an example , I copy it in meta editor an while compiling I got this error :

ANCHOR-BOTTOM -Cannot convert enum 

I find also this page with same problem in some indicator and Marco vd Heijden solved the problem but unfortunately he didn't explain how he solved it.

Here are the codes:

please help me to understand what is the problem and how it will solve.

Hi 
I was searching for the way of creating text object in chart and I find this page :

https://docs.mql4.com/constants/objectconstants/enum_anchorpoint

it seems to be exactly what I need .

in the same page there was an example , I copy it in meta editor an while compiling I got this error :

ANCHOR-BOTTOM -Cannot convert enum 

I find also this page with same problem in some indicator and Marco vd Heijden solved the problem but unfortunately he didn't explain how he solved it.

Here are the codes:

please help me to understand what is the problem and how it will solve.

ANCHOR_BOTTOM is of ENUM_ARROW_ANCHOR type

Change the ANCHOR_BOTTOM to ANCHOR_LOWER or change ENUM_ANCHOR_POINT to ENUM_ARROW_ANCHOR (whichever is needed to be used)

Thank you Mladen Rakic 

I changed ANCHOR_BOTTOM to ANCHOR_LOWER and problem Solved.
